GENERAL DESCRIPTION

This user guide describes the evaluation board hardware and soft-
ware used to evaluate the AD8555, AD8556, and
and LFCSP packages. The AD8556-EVALZ/AD8556CP-EBZ
evaluation boards allow the quick demonstration and evaluation
of the AD8555/AD8556/AD8557
mable sensor signal amplifiers.
The AD8555/AD8556/AD8557
amplifiers with programmable gain and output offset
adjustment features. The evaluation board enables a PC to
communicate with the AD8555/AD8556/AD8557. The user can
send commands to the evaluation board and read back the
programmed values for the device that is being evaluated.
This user guide supplements the information in the AD8555,
AD8556, and AD8557 data sheets, which should be consulted
in conjunction with this user guide when working with the
evaluation board.
