AD622ARZ

产品概述

The AD622ARZ is a 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. It is a complete difference or subtractor amplifier system that also provides superior linearity and common-mode rejection by incorporating precision laser-trimmed resistors. The amplifier replaces low cost, discrete, two or three operational amplifier instrumentation amplifier designs and offers good common mode rejection, superior linearity, temperature stability, reliability, power and board area consumption. The amplifier 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.
