HARDWARE DESCRIPTION
The AD8556-EVALZ/AD8556CP-EBZ evaluation boards are
designed for maximum configuration flexibility. An ac signal
can be applied to +VIN ac, and the output can be monitored
from VOUT ac. DC signals can be differentially applied between
+VIN dc and −VIN dc, and the results can be monitored using a
voltmeter at VOUT. Users can view the filter output signal at the
FILT/DIGOUT pin. The board also allows swapping of the
polarity of the inputs using the VNEG P1 and VPOS P1 switches.
COMMUNICATING WITH THE EVALUATION BOARD
Four resistors (R1A, R1B, R2A, and R2B) simulate a 100 Ω
bridge configuration. The bridge can be unbalanced using the
provided trim potentiometers (P1 and P2). The top and bottom
of the bridge are connected to VDD and VSS, respectively.
The following equipment is required:
Pulse shaping is performed on this board before applying the
data to the AD8556-EVALZ data input pin. The pulse widths
are set for 5 μs, representing the low level (0 V), and 80 μs,
representing the high level (>2.4 V). This adjustment is made
using Resistor RT0 and Resistor RT1. The trim potentiometers
are glued to their fixed positions.
The evaluation board connects to the Analog Devices SDP-B or
SDP-S board, which connects to the USB port of a PC.
Ensure that the evaluation software provided on the CD is
installed before connecting the SDP board and the evaluation
board.

ADJUSTING FOR 0 V DIFFERENTIAL INPUT
Prior to initial hardware setup and output verification, complete
the following to adjust for differential input offset:
Supply current can be monitored by using a resistor in place of
R7. Clamp voltage can be applied externally to a level or can be
set easily to VDD by placing a jumper from VCLAMP to VDD.
The SOIC/LFCSP socket is soldered for easy programming and
removal of the device. Pin 1 is the pin located in the upper lefthand corner of the socket close to R7. Make sure that the device
is placed in the socket properly. See Figure 11 for the evaluation
board schematic.

For an initial hardware setup and output verification, follow
these steps:
2.
3.
5.
Connect the evaluation board to the SDP board, which
connects to the USB port of your PC system using a USB
mini-B cable.
Position manual switches to VPOS P2 and VNEG P2.
Jumper the VCLAMP connector pin to the VDD
connector pin.

SOFTWARE
INSTALLATION
RUNNING THE SOFTWARE
To install the evaluation software on the PC,
To run the evaluation software application:
1.
1.
2.
3.
Insert the CD-ROM into the CD drive on your PC. After a
few moments, a message for the installation appears.
Double-click setup.exe. (For Windows® 7 onwards, rightclick and select Install as a system administrator.)
Follow the instructions until the software installation is
complete.
The evaluation software is developed in LabVIEW®. The
software requires a LabVIEW® runtime engine and USB drivers
for the SDP (both included in install). Install the software with
administrator access, before plugging in the SDP board. The
install detects if the SDP board has been installed previously.
2.
3.
4.
The default install location is C:\Program Files (x86)\Analog
Devices\AD855x.
For the most current data sheet, visit www.analog.com/AD8555,
www.analog.com/AD8556 or www.analog.com/AD8557.
REMOVING THE EVALUATION SOFTWARE
5.
6.
To remove the evaluation software modules,
Go to Start > Settings > Control Panel.
Double-click Add/Remove Programs and select
AD855x Evaluation Software.
11886-002
1.
2.
After the SDP board is plugged intothe PC via the USB
cable and into the AD8556-EVALZ/AD8556CP-EBZ
evaluation board via the P1 socket, run the evaluation
software. From the Start menu, click AD855x Eval, and
then click AD855xEVAL. The graphical user interface
(GUI) opens.
Select the product for which you have samples and the
connector used, and then click Start.
Set the appropriate gain and offset values, and then click
Simulate. Monitor the output as the offset is changed to
verify communication.
Program the gain between 70 and 1280 and the offset
between 0 V and 5 V. Click Simulate to load these values
into the AD8556-EVALZ/AD8556CP-EBZ and monitor
the output.
The output is input × gain and responds to the specified
configuration.
After the AD8556-EVALZ/AD8556CP-EBZ has been
simulated to the final values, click Program to
permanently blow the internal fuses to the values in the
GUI.

Select the connector and the product, and then click Start to begin evaluation.
Selects the physical connector on the SDP board that is used to connect to the evaluation board. The connectors are
labeled on the top silkscreen of the SDP board.
Selects the device under evaluation.
Configures the device according to the specified pattern. This button does not blow any fuses.
Blows fuses according to the specified pattern. Blown fuses cannot be reprogrammed.
Blows the parity fuse. The parity fuse keeps track of the state of the blown fuses. If, for any reason, the state of this fuse
is changed either intentionally or unintentionally, the parity flag is set and the alarm is set.
Permanently sets the device to the programmed gain and offset and prevents future programming. Click this button
only after selecting and programming the gain and the offset. Prior to blowing the master fuse, make sure to first
blow the parity fuse, if prompted.
Reads back the state of the programmed fuses after they have been blown. The options are as follows:
Low sense current: when dropped across a blown fuse (high impedance), creates a voltage that can trigger an internal
comparator and provide the right level in the output.
High sense current: reads back the fuse states to make sure that the fuses are blown. A code for blown fuses appears
in a pop-up box.
See the AD8555/AD8556/AD8557 data sheet for more
information on the theory of operation; simulation,
programming, and read modes; and parity error detection.
The AD8555/AD8556/AD8557 data sheet also contains more
information on programming procedures for the device.
