Analog Devices AD622 Instrumentation Amplifier Datasheet
The document describes the AD622, a low-cost, moderately accurate instrumentation amplifier designed to replace discrete two or three op-amp designs. It requires only one external resistor to set any gain between 2 and 1000, or no external resistor for unity gain. The device incorporates precision laser-trimmed resistors to provide superior linearity and common-mode rejection.
