PRODUCT DESCRIPTION
The AD622 is a low cost, moderately accurate instrumentation
amplifier that requires only one external resistor to set any gain
between 2 and 1,000. Or for a gain of 1, no external resistor
is required. The AD622 is a complete difference or subtracter
amplifier “system” while providing 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, reliabil-
ity, and board area consumption. The low cost of the AD622
eliminates the need to design discrete instrumentation amplifi-
ers to meet stringent cost targets. While providing a lower cost
solution, it also provides performance and space improvements.
