55 V, EMI-enhanced, zero drift, ultralow noise op amp
Wide operating voltage and temperature ranges, as well as the high open-loop gain and very low DC and AC errors suit the device to amplifying very small input signals and for accurately reproducing larger signals in a wide variety of applications.
The ADA4522-2’s performance is specified at 5.0 V, 30V, and 55V power supply voltages and it operates over the range of 4.5 V to 55V. It is an appropriate choice for applications using single-ended supplies of 5V, 10V, 12V,and 30V, or for applications using higher single supplies and dual supplies of ±2.5V, ±5V, and ±15V. The ADA4522-2 uses on-chip filtering to achieve high immunity to electromagnetic interference (EMI). It is fully specified over the extended industrial temperature range of −40°C to +125°C and is available in 8-lead MSOP and 8-lead SOIC packages.
Use it, ADI suggests in applications such as LCR meter/megohmmeter front-end amplifiers; Load cell and bridge transducers; Magnetic force balance scales; High precision shunt current sensing; Thermocouple/RTD sensors; or PLC input and output amplifiers.
