AD8251-EVALZ_15 Datasheet, PDF (1/4 Pages) Analog Devices – Evaluation Board for G

Evaluation Board for G = 1, 2, 4, 8,
10 MHz, 20 V/μs Programmable Gain In-Amp
AD8251-EVALZ
FEATURES
Quick evaluation
On-board gain control switches
SMA connectors for high speed gain testing
GENERAL DESCRIPTION
The AD8251-EVALZ is designed to enable quick evaluation of
the AD8251 programmable gain instrumentation amplifier
(PGIA). The evaluation board includes on-board gain setting
switches to quickly demonstrate the software gain program-
mability of the AD8251. In addition, an external logic generator
can be connected to the AD8251-EVALZ SMA ports to test the
gain control of the PGIA.
