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.
