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.
