PRODUCT DESCRIPTION

12 nV/√Hz @ 1 kHz Input Voltage Noise

0.60 ␮V p-p Noise (0.1 Hz to 10 Hz, G = 10)

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.

EXCELLENT AC CHARACTERISTICS

800 kHz Bandwidth (G = 10)

10 ␮s Settling Time to 0.1% @ G = 1–100

1.2 V/␮s Slew Rate

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.
