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.

0.15% gain accuracy: G = 1

125 µV maximum input offset voltage

1.0 µV/°C maximum input offset drift

5 nA maximum input bias current

66 dB minimum common-mode rejection ratio: G = 1

Noise

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.

12 nV/√Hz @ 1 kHz input voltage noise

0.60 µV p-p noise: 0.1 Hz to 10 Hz, G = 10

AC characteristics

800 kHz bandwidth: G = 10

10 µs settling time to 0.1% @ G = 1 to 100

1.2 V/µs slew rate
