ADA4522-2ARZ

The ADA4522-2 is a dual channel, zero drift op amp 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 device well suited for amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications. The ADA4522-2 performance is specified at 5.0 V, 30 V, and 55 V power supply voltages and it operates over the range of 4.5 V to 55 V. It is an excellent selection 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 ADA4522-2 uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI). The ADA4522-2 is fully specified over the extended industrial temperature range of −40°C to +125°C and is available in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14-lead TSSOP packages. Applications LCR meter/megohmmeter front-end amplifiers Load cell and bridge transducers Magnetic force balance scales High precision shunt current sensing Thermocouple/RTD sensors PLC input and output amplifiers
