Description

The ADA4522-1 /ADA4522-2/ADA4522-4are single/dual/quad channel, zero drift op amps with low noise and power, ground sensing inputs, and rail-to-rail output, optimized for total accuracy over time, temperature, and voltage conditions. The wide operating voltage and temperature ranges, as well as the high open-loop gain and very low dc and ac errors make the devices well suited for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications.The ADA4522-1 / ADA4522-2 / ADA4522-4 performance is specified at 5.0 V, 30 V, and 55 V power supply voltages. These devices operate over the range of 4.5 V to 55 V, and are excellent for applications using single-ended supplies of 5 V, 10 V, 12 V, and 30 V, or for applications using higher single supplies and dual supplies of ±2.5 V, ±5 V, and ±15 V. The ADA4522-1 / ADA4522-2 / ADA4522-4 use on-chip filtering to achieve high immunity to electromagnetic interference (EMI).The ADA4522-1 / ADA4522-2 / ADA4522-4 are fully specified over the extended industrial temperature range of −40°C to +125°C and are available in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages.APPLICATIONSInductance, capacitance, and resistance (LCR) meter/megohmmeter front-end amplifiersLoad cell and bridge transducersMagnetic force balance scalesHigh precision shunt current sensingThermocouple/resistance temperature detector (RTD) sensorsProgrammable logic controller (PLC) input and output amplifiers
