Product Introduction

The ADA4522-1/ADA4522-2/ADA4522-4 are 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 5.0V, 30V, and 55V power supply voltages. These devices operate over the range of 4.5V to 55V, and are excellent for applications using single-ended supplies of 5 V, 10V, 12V, and 30V, or for applications using higher single supplies and dual supplies of ±2.5V, ±5V, and ±15V. The ADA4522-1/ ADA4522-2/ADA4522-4 use on-chip filtering to achieve high immunity to electromagnetic interference (EMI).
