GENERAL DESCRIPTION
The ADIS16003/PCB is a simple evaluation board that provides
convenient access to the ADIS16003 using a standard 2mm,
2x6, connector interface. These connectors can be accessed
using a variety of cable options, including standard 1mm ribbon
cables. The ADIS16003/PCB is designed to be evaluated in an
existing digital platform (MCU, DSP, FPGA, PLD, etc) or as
part of the ADISEVAL system. Four mounting holes (sized for
2-56 or 2mm screws) have been provided to secure the board
during evaluation.
CIRCUIT DESCRIPTION
The schematic, layout and parts list for the ADIS16003/PCB can
be found in Figure 1, Figure 2, and Table 1.
The ADIS16003’s digitized outputs can be accessed using the 4-
wire serial port interface (SPI) signals on J1: SCLK, CS, DOUT
and DIN. For specific information on using the ADIS16003’s
SPI interface, refer to the ADIS16003 datasheet. C1 is not
populated but provides opportunity to add a filtering capacitor
for helping clean up noisy power supply inputs. C2 and C3 are
not installed but provide the ability to reduce the bandwidth on
each axis. See the ADIS16003 datasheet for more details.

SPECIAL NOTES ON HANDLING
Note that the ADIS16003/PCB is not reverse polarity protected.
Reversing the power supply or applying inappropriate voltages
to any pin (outside the Absolute Maximum Ratings in the
ADIS16003 data sheet) may damage the ADIS16003/PCB.
