GENERAL DESCRIPTION Analog Devices' ADS20 first instrumentation amplifier manufactured integrated circuit form. closed loop gain block with differential inputs accurately predictable input-to-output gain relationship. 20's performance unlike that conventional operational amplifiers because internal feedback design which permits gain adjustment from 1000 varying value single resistor. Further, high input impedance achieved both inputs both input impedance CMRR remain high gain settings. AD520 performs like modular instrumentation ampliFrer. Because monolithic construction, however, cost significantly below that modules, becomes even lower

with larger quantity requirements. ADs20 features bias offset currents, high gain linea-ity, excellent frequency response, short circuit proteC1~d offset voltage nullable. Thus ideally suited general purpose, high accuracy amplifier requirements. small size, cost, complete-on~-chip ease application offer circuit designer attractive alternative both modular instrumentation amplifier packages, user-wired collections amps high-precision external components. ADs20 finds excellent application amplification level signals from bridge circuits, thermocouples, strain gauges, other transducers. Other applications include chart recorders, line reviewers, medical electronics. increased versarility, amplifier remote sense terminal current-
