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).
The ADA4522-1/ADA4522-2/ADA4522-4 are fully specified over the
extended industrial temperature range of −40°C to +125°C and are
available in 8-lead MSOP, 8-lead SOIC, 14-lead SOIC, and 14‑lead
TSSOP packages.
