GENERAL DESCRIPTION

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 5.0 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).
