GENERAL DESCRIPTION
The AD622 is a low cost, moderately accurate instrumentation
amplifier in the traditional pin configuration that requires only
one external resistor to set any gain between 2 and 1000. For a
gain of 1, no external resistor is required. The AD622 is a
complete difference or subtractor amplifier system that also
provides superior linearity and common-mode rejection by
incorporating precision laser-trimmed resistors.
The AD622 replaces low cost, discrete, two or three op amp
instrumentation amplifier designs and offers good common-
mode rejection, superior linearity, temperature stability,
reliability, power, and board area consumption. The low cost of
the AD622 eliminates the need to design discrete
instrumentation amplifiers to meet stringent cost targets. While
providing a lower cost solution, it also provides performance
and space improvements.
