A | Page 2 of 28 Evaluation Board User Guide EVAL-ADAS3023EDZ EVALUATION BOARD HARDWARE OVERVIEW The EVAL-ADAS3023EDZ evaluation board is designed to offer simple evaluation of this integrated device. From a block diagram perspective, the board uses a set of analog input test points (or an IDC header), some passive footprints for RC filtering and external reference, the ADAS3023 device, a serial interface to the on-board FPGA, and power that can be supplied locally or via EVAL-CED1Z or externally. Note that the ADAS3023 device also has an on-chip reference; however, external circuitry is provided for those who need to test other suitable options. A rising edge on CNV samples the differential analog inputs of a channel or channel pair. The ADAS3023 configuration register allows the user to configure the number of enabled channels, the differential input voltage range, and the interface mode using the evaluation board and software as detailed in this user guide. Complete specifications for the ADAS3023 are provided in the product data sheet and should be consulted in conjunction with this user guide when using the evaluation board. Full details on the EVAL-CED1Z are available on the Analog Devices website. The small prototyping area can be useful for building additional circuitry, if desired. Each block has a specific function as defined in the following sections. Single-Ended Signals 1 0 V to 1 V 0 V to 2.5 V 0 V to 5 V 0 V to 10 V DEVICE DESCRIPTION Manufactured using the Analog Devices patented high voltage iCMOS® process, the ADAS3023 is a complete data acquisition system (DAS) on a single chip that is capable of converting two channels simultaneously up to 500 kSPS. This part allows the differential voltage range up to ±20.48 V when using ±15 V supplies. The ADAS3023 can resolve the full-scale differential voltages of ±2.56 V, ±5.12 V, ±10.24 V, and ±20.48 V, and it can be configured to sample two, four, six, or eight channels simultaneously. The key difference between the ADAS3022 and ADAS3023 is that the ADAS3023 does not offer the AUX± channels and temperature sensor (using the CFG register) In addition, the BUSY/SDO2 (Pin 19) functionality of the ADAS3023 is different. 1 Input Range, VIN (V) ±1.28 V ±2.56 V ±5.12 V ±10.24 V See the ADAS3023 data sheet for more information JUMPERS, SOLDER PADS, AND TEST POINTS Numerous solder pads and test points are provided on the evaluation board and are detailed fully in Table 4, Table 5, and Table 6. Note the nomenclature for this evaluation board for a signal that is also connected to an IDC connector would be signal_I. The two 3-pin user selectable jumpers are used for the ADCs reference selection and are fully described in the Reference section. ANALOG INTERFACE The ADAS3022/ADAS3023 devices become pin compatible and can be exchanged on the same footprint if the no connect (NC) pins (Pin 14/Pin 29/Pin 30 on the ADAS3022) and AUX± (Pin 5 and Pin 40 on the ADAS3022) are tied to AGND, and if the SDO2 (using the CFG register) of the ADAS3023 is not enabled, so that the user can actually work with either one of these options using the same evaluation board. Leaving these pins floating is not recommended. Note that the differential paired mode does not exist in the ADAS3023 and, therefore, its 2/4/6/8 channels are always referenced to COM. The ADAS3023 is an ideal replacement for a typical 16-bit, simultaneous sampling precision data acquisition system that simplifies the design challenges by eliminating signal buffering, level shifting, amplification/attenuation, common-mode rejection, settling time, or any of the other analog signal conditioning challenges while allowing smaller form factor, faster time to market, and lower costs. Data communication to and from the ADAS3023 occurs asynchronously without any pipeline delay using a common 4-wire serial interface compatible with SPI, FPGA, and DSP. Table 1. Typical Input Range Selection The analog interface is provided with test points for each of the analog inputs IN[7:0] and COM (that is, IN0_I is common to both the test point and to P1). The passive device footprints can be used for filtering, if desired. A simple RC filter made up of 22 Ω and 2700 pF NPO capacitors is provided. Note that the use of stable dielectric capacitors, such as NPO or COG, is required in the analog signal path to preserve the ADAS3023 distortion. Using X5R or other capacitors in the analog signal path greatly reduces the performance of the system. Also, note that many bench top arbitrary waveform generators (AWGs) use 12-bit or 14-bit digital-to-analog converter outputs such that the 16-bit ADAS3023 devices digitize this directly resulting in erroneous looking data. If such an AWG is used, a high-order band-pass filter should be used to filter the unwanted noise from these sources. The P31 center pin is connected to the ADAS3023 COM input, which can be routed to P1 or GND using P31. For channel to COM configuration, set the jumper across Pin 1 and Pin 2 to route to P1. For channel pairs configuration, set the jumper across Pin 2 to Pin 3 to route to GND. This is useful for singleended applications. For dynamic performance, an FFT test can be done by applying a very low distortion ac source, such as an Audio Precision Rev. A | Page 3 of 28 EVAL-ADAS3023EDZ Evaluation Board User Guide System 2702. This source can be set for balanced or unbalanced, and can be floated or grounded depending on the user’s choice. FPGA The on-board FPGA performs a number of digital functions, one of them being the sample rate conversion controlled using the software. Another function is deserializing the serial conversion results as the CED data capture board uses a 16-bit parallel interface. If desired, the deserialized data can be monitored on the 96-pin edge connecter P1, BD[15:0]. The CED uses a buffered busy signal, BBUSY, as the general interrupt for the data transfer to the CED board. The FPGA also provides the necessary ADAS3023 asynchronous control signals for RESET and power down (PD). The signals from the FPGA to the ADAS3023 can be bypassed by modifying the default solder pad connections. As shown in Figure 2, each digital signal on the ADAS3023 is connected to the larger (top) pad of the three. The default configuration is the small pad and larger pad (no text) which connects the FPGA to the ADAS3023 (CNV, BUSY, and SDO signals shown). The labeled pads, CNV_I, BUSY_I, SDO_I, and so on, are the signals that are routed to P3. To use P3 instead of the FPGA, unsolder the default connections and resolder from the large pad to the xxx_I pads. The FPGA will remain powered; however, if all the signals are bypassed in this fashion, it will not have any influence on the ADAS3023. DEFAULT the ADC REF1 or REF2 (REFx) pin directly or it can also be buffered with U20, the AD8032; both of these are set to the factory default setting. Table 2. Factory Reference Jumper Configuration Jumper Setting P5 P9 REFIN to GND1 REF to BUF (U20) 1 The connection is made through R102 = 10 k to GND. To use another reference source, there are two methods: • For an external unbuffered reference, remove the P9 jumper and connect a source to the REF test point. • Since the ADR434 is a standard 8-lead SOIC, it can also be removed and replaced with the user’s reference. In this case, the user reference and the U20 AD8032 buffer can be used as a reference source. Internal 4.096 V Reference The ADC has an internal 4.096 V precision reference and can be used on most applications. When enabled, 4.096 V will be present on the ADAS3023 REFx pin and test point, REF. In addition, a voltage will also be present on the ADAS3023 REFIN pin and test point, REFIN. The voltage present on REFIN can be used for other purposes, such as to provide the bias voltage; however, it would need a suitable buffer as the output impedance of the REFIN is on the order of a few kilo ohms and loading this voltage down will degrade the internal reference’s performance. Table 3. Internal Reference Jumper Configuration CONNECTION TO P3 Jumper Setting P5 P9 Open Open 11221-003 Note that the ADAS3023 configuration register needs to be updated either using the included software or by writing the appropriate bits to enable the internal reference. Figure 2. Digital Interface Solder Pads—Partial View Serial Interface Internal Reference Buffer The 4-wire serial interface consisting of CS, DIN, SCK, and SDO is present on the digital interface test points and is controlled by the FPGA. The FPGA can be bypassed by using the solder pads. The internal reference buffer is useful when using an external 2.5 V reference. When using the internal reference buffer, applying 2.5 V to REFIN, which is directly connected to the ADC’s REFIN pin, produces 4.096 V at the ADCs REFx pin and REF test point. REFERENCE The ADAS3023 has an internal 4.096 V reference, along with an internal buffer, useful for using an external reference or one can use an external 4.096 V reference directly, such as the ADR434 provided on the evaluation board. The evaluation board can be configured to use any of these references. Two jumpers (P5 and P9) are used for setting the reference in conjunction with software control. External Reference–Factory Configuration The evaluation board includes the ADR434, A1, which is a 4.096 V precision voltage reference. This reference can drive POWER SUPPLIES AND GROUNDING The on-board ADP3334 low dropout regulators are provided for 2.5 V, 3.3 V, and 5 V and also for the FPGA I/O supply which is user configurable and set to 3.3 V by default. The FPGA core is supplied by a pair of ADP1715 devices set for 1.2 V. Additional power is supplies via the CED board for an alternative +5 V analog and digital 3.3 V/5 V digital through P4. The ADAS3023 requires ±15 V supplies for VDDH and VSSH. These must be supplied by the user using a standard lab supply ensuring that the return paths are at the same potential. Refer to Rev. A | Page 4 of 28 Evaluation Board User Guide EVAL-ADAS3023EDZ CN-0201 for the complete information on generating these ±15 V supplies from a +5 V single supply. The differential input common-mode voltage (VCM) range changes according to the maximum input range selected and the high voltage power supplies (VDDH and VSSH). In other words, the specified operating input voltage of any input pin requires 2.5 V of headroom from the VDDH and VSSH supplies. The evaluation board ground plane consists of a solid plane on one PCB layer shared on another layer with the power plane. To attain high-resolution performance, the board was designed to ensure that all digital ground return paths do not cross the analog ground return paths, that is, all analog on one side and digital on the other. EVALUATION BOARD SCHEMATICS/PCB LAYOUT The evaluation board is a 6-layer board carefully laid out and tested to demonstrate the specific high accuracy performance of the ADAS3023 devices. The Evaluation Board Schematics and Artwork section of this user guide shows the schematics of the evaluation board.

A | Page 9 of 28 EVAL-ADAS3023EDZ Evaluation Board User Guide POWERING UP THE BOARD 11221-009 The evaluation board, as configured from the factory, uses the local LDOs for power where necessary. A ±15 V dc lab supply must be connected to the board. Test points (yellow and white) are provided for these external supplies. Figure 9. Test Points RUNNING THE SOFTWARE WITH THE HARDWARE CONNECTED The evaluation board includes software for analyzing the ADAS3023. The EVAL-CED1Z is required when using the software. The software is used to perform the following tests: • • • Histogram tests for determining code transition noise (dc) Fast Fourier transforms (FFT) for signal-to-noise ratio (SNR), SNR and distortion (SINAD), total harmonic distortion (THD), and spurious free dynamic range (SFDR) Time domain analysis This evaluation software should be located at <local_drive>:\Program Files\Analog Devices\ADAS3023 Evaluation Software. In order to launch the software, click Start>All Programs>Analog Devices\ADAS3023 Evaluation Software. You can then apply the signal source and capture the data. To uninstall the program, click Start>Control Panel>Add or Remove Programs>Analog Devices ADAS3023 16-Bit, 8-Channel Simultaneous Sampling Data Acquisition System. Refer to Figure 10 to Figure 19 for further details and features of the software. DC TESTING–HISTOGRAM This tests the ADC for the code distribution for dc input and computes the mean and standard deviation, or transition noise, of the converter and displays the results. Raw data is captured and passed to the PC for statistical computations. To perform a histogram test, select Histogram from the test selection window and click on Start. To test dc values, apply a source to any of the analog inputs IN[7:0]_I either via test points or P1. Note that 0805 and 0603 SMT pads are provided in each signal path and can be used for filtering the source, if necessary. AC TESTING This tests the traditional ac characteristics of the device and displays a fast Fourier transform (FFT) of the result. As in the histogram test, raw data is captured and passed to the PC where the FFT is performed displaying SNR, SINAD, THD, and SFDR. The data can also be displayed in the time domain. To perform an ac test, apply a sinusoidal signal to the analog inputs. Low distortion, better than 97 dB, is required to allow true evaluation of the part. Note than many bench-top signal generators are at best 14-bit digital to analog converter (DAC) outputs and the ADAS3023 is 16-bits. Simply connecting a source of this resolution results in what would appear to be incorrect displayed results (numerous harmonics and spurs). To alleviate this, one possibility is to filter the input signal from the ac source. There is no suggested band-pass filter, but consideration should be taken in the choice. Note that a passive filter also provides dc blocking and if any dc common mode is to be preserved, it would have to take place after the filtering. Rev.

Serial Data Output 2 (SDO2) Option: The ADAS3023 busy signal is always output on the BUSY/SDO2 pin when CS is logic high. If SDO2 is enabled when CS is brought low after the EOC, the SDO outputs the data from Channel 0, Channel 1, Channel 2, and Channel 3 and SDO2 outputs the data from Channel 4, Channel 5, Channel 6, and Channel 7 after 16 SCK rising edges. The conversion result output on this pin synchronizes to the SCK falling edges. Click SDO2 DISABLED once to display SDO2 ENABLED. Update CFG: If the default configuration (channel, channel configuration, reference, and so on) is acceptable, clicking Update CFG writes to the EVAL-ADAS3023EDZ 4. 5. Evaluation Board User Guide ADAS3023 configuration register (CFG). Note that after changing any of the CFG register, this button must be clicked for the new setting to take effect. The CFG controls (labeled 4 in Figure 10) are used to set the CFG. See the Software Controls section. Sampling Frequency is used to set the sample frequency. Enter the sample rate in kilohertz. Units, such as .5 k (case sensitive) for 500,000 Hz (maximum 500 kSPS), can be used. Configuring the ADAS3023 Device Programmable Gain The most useful and innovative feature of the ADAS3023 is the on-chip programmable gain instrumentation amplifier, which allows four (±2.56 V to ±20.48 V) input ranges. Select the appropriate setting for the input voltage span. Do not include any common-mode signals, which are rejected. Note that the ADAS3023 device does not need the usual level shifting that is common in SAR ADC systems. The ADAS3023 device can accommodate any input type, fully differential, single ended, bipolar, and so on. The ADAS3023 device is configurable using a 16-bit on-chip register, CFG (refer to the device data sheet for more details). Remember to select Update CFG after choosing CFG details for the new setting to take place. Configure all the selections and then select Update CFG. Input Channel 11221-113 11221-112 To select the input channel, make a selection from the pulldown menu. Figure 11. Input Channel Figure 13. Programmable Gain Channel Pairing The channels can be paired (up to 4 maximum) or all channels can be referenced to the COM input. Note that any input channel including COM has an absolute input range of VDDH − 2.5 V and VSSH + 2.5 V (± high voltage supplies, usually external). Software Controls Within any of the chart panels, these controls are used to control the display. Locks the graph axis to automatically fit the data. Uses last axis set by user. , Rescales the axes to the automatic values. , Set the axes properties, such as format, precision, color, and so on. Displays the cursor. Is used for zooming in and out. 11221-111 Is used for panning. Figure 12. Channel Pairing Is used to set various graph properties such as graph type, colors, lines, and so on. Rev.
