The ADA4522-2 is a dual, zero-drift, low noise, low power, rail-to-rail output amplifier optimized for total accuracy over time, temperature and voltage conditions. The wide operating voltage and temperature ranges and the high open loop gain and very low DC and AC errors make it 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 guaranteed at 5.0 V, 30 V, and 55 V power supply voltages. It is an excellent selection for applications using single ended supplies of 5V, 10V, 12V and 30V or higher single supplies and dual supplies of ±2.5V, ±5V and ±15V. The ADA4522-2 utilizes on-chip filtering to achieve high immunity to electromagnetic interference.
The ADA4522-2 is fully specified over the extended industrial temperature range (?40°C to +125°C) and is available in an 8-lead MSOP and SOIC packages.
