EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
POWER SUPPLIES
The AD7944 is a 14-bit, 2.5 MSPS successive approximation
(SAR) ADC. The AD7985 is a 16-bit, 2.5 MSPS SAR ADC. The
AD7986 is an 18-bit, 2 MSPS SAR ADC.
The power (12 V) for the EVAL-AD7944FMCZ/EVALAD7985FMCZ/EVAL-AD7986FMCZ evaluation boards comes
through a 160-pin FMC connector, J7, from the EVAL-SDPCH1Z. The user also has the option of using an external 12 V
supply to power the evaluation board. On-board regulators
generate the required levels from the applied 12 V rail. The
ADP7118 (U18) supplies 7.5 V for the +VS pin of the ADC
driver amplifiers (ADA4899-1, ADA4897-1, or AD8021), the
external reference ADR4550 (U5), the ADR4525 (U8), and the
ADR3412. Another ADP7118 (U10) supplies 5 V for BVDD
(U1), the ADP2370 (U2), and the ADM7160 (U3 and U12).
The ADP2370 (U2), in turn, directly generates −3.0 V or
connects to the ADP7182 to generate −2.5 V for the −VS pin of
the amplifier. The ADM7160 (U3 and U12) provides 2.5 V for
DVDD and VIO (U1). The user also can use external bench top
supplies to power the on-board amplifiers. The 3.3 V supply for
the EEPROM (U7) comes from the EVAL-SDP-CH1Z through
a 160-pin FMC connector, J7. Each supply is decoupled where it
enters the board and again at each device. A single ground
plane is used on this board to minimize the effect of high
frequency noise interference.
These ADCs are low power and high speed and include an
internal conversion clock, an internal reference (and buffer),
error correction circuits, and a versatile serial interface port. On
the rising edge of CNV, each ADC samples an analog input, IN+,
between 0 V and REF with respect to the ground sense, IN−.
The ADCs feature a very high sampling rate turbo mode
(TURBO is high) and a reduced power normal mode (TURBO
is low) for low power applications where the power is scaled
with the throughput.
Full descriptions of the AD7944, AD7985, and AD7986 are
available in the respective product data sheets, which should be
consulted in conjunction with this user guide when using the
evaluation boards. Full details on the EVAL-SDP-CH1Z are
available at the SDP board product page.

SERIAL INTERFACE
ANALOG INPUTS
The EVAL-AD7944FMCZ/EVAL-AD7985FMCZ/EVALAD7986FMCZ evaluation boards use the serial interface
connection to the EVAL-SDP-CH1Z. The EVAL-AD7944FMCZ/
EVAL-AD7985FMCZ/EVAL-AD7986FMCZ have two different
data reading options: read during conversion and read during
acquisition, both of which can operate in 3-wire and 4-wire
serial interface modes. When using the serial interface, the
voltage level shifter option and the external compatible serial
interface options are supported. The serial interface requires
five pins (SDI, SCK, SDO, TURBO, and CNV) connected
between each ADC and the digital host.
The analog inputs applied to the EVAL-AD7944FMCZ/EVALAD7985FMCZ/EVAL-AD7986FMCZ evaluation boards are the
J1 and J2 SMA (push on) connectors. These inputs are buffered
with dedicated, discrete driver amplifier circuitry (U15 and U16
or U14), as shown in Figure 1.

The circuit allows different configurations, input range scaling,
filtering, the addition of a dc component, the use of a different
op amp, and a differential amplifier and supplies. The analog
input amplifiers are set as unity-gain buffers at the factory. The
positive rails of the driver amplifiers (U14, U15, and U16) are
driven from 7.5 V (from the ADP7118, U18), and the negative
rails are driven from −3.0 V. The positive rails of the other reference
buffers (U4 and U11) are driven from 7.5 V, and the negative
rails are grounded; these rails can be changed as required. The
range of possible supplies is listed in Table 3. The default
configuration sets both U15 and U16 at midscale generated
from a buffered reference voltage (VCM) of the ADR4550 (U5).
The evaluation board is factory configured to provide either a
single-ended path or a fully differential path, as described in
Table 1. Because the AD7986 is differential, both inputs and
amplifier circuits are used to buffer the IN+ and IN− inputs of
the ADCs. For the AD7944 and the AD7985 evaluation boards,
only the J2, U15, and associated circuitry are used in the path.
For dynamic performance, an FFT test can be performed by
applying a very low distortion source. For low frequency testing,
use the audio precision source. Set the outputs for balanced and
floating. Different sources can be used, though most are singleended and use a fixed output resistance.
Because the evaluation board uses the amplifiers in unity gain,
the noninverting input has a common-mode input with a series
590 Ω resistor, which must be taken into account when directly
connecting a source (voltage divider).
REFERENCE OPTIONS
The AD7944, AD7985, and AD7986 each have an internal
4.096 V reference together with an internal buffer that can be
used with an external reference; the devices can also use an
external 5.0 V or 2.048 V reference directly. The EVALAD7944FMCZ/ EVAL-AD7985FMCZ/EVAL-AD7986FMCZ
evaluation boards can be configured to use any of these
references. The jumpers and linkers used to set the reference are
shown in Table 1.
External Reference: Default Configuration
The EVAL-AD7944FMCZ/EVAL-AD7985FMCZ/EVALAD7986FMCZ evaluation boards include an external 5 V and
2.048 V reference. This reference can drive the ADCs and the
REF pin directly, or it can be buffered with the AD8031; the
factory default setting is 5 V and buffered with the AD8031.
The best attainable signal-to-noise ratio (SNR) is achieved by
using the maximum reference voltage of 5 V. Refer to the
AD7944, AD7985, and AD7986 data sheets for more details.

Internal 4.096 V Reference
BASIC HARDWARE SETUP
The AD7944/AD7985/AD7986 ADCs have an internal 4.096 V
precision reference that can be used on most applications.
Connecting PDREF to GND enables the internal reference. When
the internal reference is enabled, a 4.096 V as well as a 1.2 V band
gap are present on the ADC REF pin and test point. When using
this method, R14 and R17 must be removed to achieve the best
performance. External sources must not be connected to these
test points because they are directly connected to the ADC pins.
The EVAL-AD7944FMCZ/EVAL-AD7985FMCZ/EVALAD7986FMCZ evaluation boards connect to the (EVAL-SDPCH1Z) system demonstration board. The EVAL-SDP-CH1Z
board is the controller board, which is the communication link
between the PC and the main evaluation board.
Internal Reference Buffer
The internal reference buffer is useful when using an external 1.2 V
reference. When using the internal reference buffer, applying 1.2 V
reference ADR3412 (U13) to REFIN, which is directly connected
to the REFIN pin of the ADC, produces 4.096 V at the REF pin of
the ADC. R14 and R17 must be removed to achieve the best
performance. External sources must not be connected to these
test points because they are directly connected to the ADC pins.
Figure 1 shows a photograph of the connections between the
EVAL-AD7944FMCZ/EVAL-AD7985FMCZ/EVALAD7986FMCZ daughter board and the EVAL-SDP-CH1Z
controller board.

LAYOUT GUIDELINES
When laying out the printed circuit board (PCB) for the ADC,
follow these recommended guidelines to obtain the maximum
performance from the converter.
•
•
•
•
•
•
•
Solder the ADC exposed paddle (Pin 21) directly to the
PCB, and connect the paddle to the ground plane of the
board using multiple vias.
Decouple all the power supply pins (AVDD, BVDD, and
VIO) and the REF pin with low ESR and low ESL ceramic
capacitors, typically 10 µF and 100 nF, placed close to the
DUT (U1) and connected using short, wide traces. This
provides low impedance paths and reduces the effect of
glitches on the power supply lines.
The ADC voltage reference inputs (REF) have a dynamic
input impedance and must be decoupled with minimal
parasitic inductances, by placing the reference decoupling
ceramic capacitor close to, ideally right up against, the REF
and REFGND pins and connecting them with wide, low
impedance traces.
Separate analog and digital sections and keep power supply
circuitry away from the ADC.
Avoid running digital lines under the device as well as
crossover of digital and analog signals, because these
couple noise into the ADC.
Do not run fast switching signals, such as CNV or clocks,
near analog signal paths.
Remove the ground and power plane beneath the input
(including feedback) and output pins of the amplifiers (U14,
U15, and U16), because they create an undesired capacitor.

SOFTWARE OPERATION
Interface Selection
This section describes the full software operation and all the
windows that appear. When the software is launched, the main
software window opens, and the software searches for hardware
connected to the PC. The user software window launches as
shown in Figure 19. The labels listed in this section correspond
to the numbered labels in Figure 19.
The Interface Selection drop-down menu, Label 8 in Figure 19,
provides options for using 3-wire or 4-wire mode, reading
during or reading after conversion, and no busy signal mode.
File Menu
The File menu, Label 1 in Figure 19, has the following options:
•
•
•
•
•
Save Captured Data: saves data to a .CSV file
Load Captured Data: loads data for analysis
Take Screenshot: saves the current screen
Print: prints the window to the default printer
Exit: closes the application
The options for using the external reference or internal reference
are controlled by the Voltage Reference drop-down menu,
Label 9 in Figure 19. The default value is set to 5 V (external
reference and external buffer). The other voltage reference
options are 4.096 V (external or internal reference) and 2.048 V
(external reference). When using the external reference, it is
recommended to use an on-board AD8031 as an external
reference buffer.
Turbo Mode
Edit Menu
The Edit menu, Label 2 in Figure 19, provides the Initialize to
Default Values option, which resets the software to its initial state.
Help Menu
The Turbo Mode button, Label 10 in Figure 19, provides the
options of Turbo On or Turbo Off (normal mode). Note that
the throughput must be manually changed when changing modes.
Throughput
The Through Output field, Label 11 in Figure 19, controls the
throughput. The default throughput (sampling frequency) is
2000 kSPS. The user can adjust the sampling frequency; however
there are limitations around the sample frequency related to the
SCLK frequency applied. The sample frequency must be at least
200 kSPS. The AD7985 is capable of operating a maximum sample
frequency of 2500 kSPS in reading during conversion turbo mode.

board is connected. In Figure 19, the connected evaluation
board is the EVAL-AD7985FMCZ.
Samples
If the user enters a value exceeding the maximum capacity of
the device, the software indicates this, and the user must revert
to the maximum sample frequency.
Tabs
There are four additional tabs available for displaying the data
in different formats.
From the Samples drop-down menu, Label 5 in Figure 19,
select the number of samples to analyze when running the
software; this number is limited to 1,048,576 samples.
Single Capture and Continuous Capture
Clicking Single Capture , Label 6 in Figure 19, performs a
single capture, whereas clicking Continuous Capture, Label 7
in Figure 19, performs a continuous capture from the ADC.

DC TESTING—HISTOGRAM
AC TESTING—HISTOGRAM
Figure 21 shows the Histogram tab. The histogram can be used
to test the ADC for the code distribution for dc input, compute
the mean and standard deviation or transition noise of the
converter, and display the results. Raw data is captured and
passed to the PC for statistical computations.
The histogram can also be used to test the ADC for the code
distribution for ac input, compute the mean and standard deviation
or transition noise of the converter, and display the results. Raw
data is captured and passed to the PC for statistical computations.
To perform a histogram test, click the Histogram tab, then click
Single Capture or Continuous Capture.
A histogram test can be performed without an external source
because the evaluation board has a buffered VREF/2 source at the
ADC input.
To test other dc values, apply a source to the J1 and J2 inputs.
The signal may need to be filtered so that the dc source noise is
compatible with that of the ADC.
To perform a histogram test, click the Histogram tab, then click
Single Capture or Continuous Capture.
An ac histogram requires a quality signal source applied to the
input J1/J2 connectors.
Figure 21 shows the histogram for a 20 kHz sine wave applied to
the ADC input and the results calculated.
The Histogram Analysis boxes, Label 1 in Figure 21, show the
various measured values for the data captured.

AC TESTING—FFT CAPTURE
Figure 22 shows the FFT tab. This tests the traditional ac
characteristics of the converter and displays a fast Fourier
transform (FFT) of the results. As in the histogram test, raw
data is captured and passed to the PC where the FFT is performed
to display the signal-to-noise ratio (SNR), signal-to-noise-anddistortion ratio (SINAD), total harmonic distortion (THD),
and spurious-free dynamic range (SFDR).
To perform an ac test, apply a sinusoidal signal to the evaluation
board at the SMA inputs, J1 and J2. A very low distortion, better
than 130 dB input signal source (such as audio precision) is
required to allow true evaluation of the device. One possibility
UG-727
is to filter the input signal from the ac source. There is no
suggested band-pass filter, but carefully consider the choices.
Furthermore, if using a low frequency band-pass filter when the
full-scale input range is more than a few volts peak-to-peak, it is
recommended to use the on-board amplifiers to amplify the signal,
thus preventing the filter from distorting the input signal.
Figure 22 displays the results of the captured data.
FFT Analysis shows the input signal information (Label 1), as
well as the performance data, including SNR, dynamic range, THD,
SINAD, and noise performance (Label 3).
Show Harmonic Content displays the fundamental frequency and
amplitude in addition to the second to fifth harmonics (Label 2).

TROUBLESHOOTING
This section provides recommendations on how to prevent and
troubleshoot problems encountered with the software and the
hardware.
SOFTWARE
HARDWARE
If the software does not read any data back, take the following steps:
•
Follow these recommendations for the evaluation software:
•
•
•
•
•
•
Always install the software prior to connecting the
hardware to the PC.
Always allow the install to fully complete (the software
installation is a two part process: installing the ADC software
and the SDP drivers). This may require a restart of the PC.
When you first plug in the EVAL-SDP-CH1Z board via the
USB cable provided, allow the new Found Hardware Wizard
to run. Though this may take time, do this prior to starting
the software.
If the board does not appear to be functioning, ensure that the
ADC evaluation board is connected to the EVAL-SDP-CH1Z
board and that the SDP board is recognized in the Device
Manager, as shown in Figure 16.
If connected to a slower USB port where the EVAL-SDPCH1Z cannot read quickly, a timeout error may occur. In
this case, it is advised not to read continuously or, alternatively,
to lower the number of samples taken.
Note that when reading continuously from the ADC, the
recommended number of samples is up to 1,048,576.
•
•
•
•
With the 12 V wall wart plugged in to the EVAL-SDP-CH1Z
board, check that the voltage applied is within the ranges
shown in Table 3.
Using a digital multimeter (DMM), measure the voltage
present at 12 V and the VADJ test points, which should
read 12 V and 2.5 V, respectively. The +12V_FMC LED of
the evaluation board and the LEDs of the EVAL-SDP-CH1Z
board (FMC_PWR_GO, SYS_PWR, FPGA_DONE,
BF_POWER, LED0, and LED2) should all be lit.
Launch the software and read the data. If nothing happens,
exit the software.
Remove the 12 V wall wart and USB from the EVAL-SDPCH1Z board, and then reconnect them and relaunch the
software.
If an error occurs, check that the evaluation board and the
EVAL-SDP-CH1Z board are connected together so that the
EVAL-SDP-CH1Z is recognized in the Device Manager, as
shown in Figure 16.
Note that when working with the software in standalone/offline
mode (no hardware connected), if you later choose to connect
hardware, first close and then relaunch the software.
