GENERAL DESCRIPTION
The AD8601 and AD8602 are single and dual rail-to-rail input
and output single supply amplifiers featuring very low offset voltage
and wide signal bandwidth. These amplifiers use a new, patented
trimming technique that achieves superior performance without
laser trimming. All are fully specified to operate from 3 V to 5 V
single supply.
The combination of low offsets, very low input bias currents, and
high speed make these amplifiers useful in a wide variety of applica-
tions. Filters, integrators, diode amplifiers, shunt current sensors,
and high impedance sensors all benefit from the combination of
performance features. Audio and other ac applications benefit from
the wide bandwidth and low distortion. For the most cost-sensitive
applications the D grades offer this ac performance with lower dc
precision at a lower price point.
Applications for these amplifiers include audio amplification for
portable devices, portable phone headsets, bar code scanners,
portable instruments, and multipole filters.

The ability to swing rail-to-rail at both the input and output
enables designers to buffer CMOS ADCs, DACs, ASICs, and
other wide output swing devices in single supply systems.
The AD8601 and AD8602 are specified over the extended industrial
(–40°C to +125°C) temperature range. The AD8601, single, is avail-
able in the tiny 5-lead SOT-23 package. The AD8602, dual, is avail-
able in 8-lead MSOP and narrow SOIC surface-mount packages.
SOT and µSOIC versions are available in tape and reel only.
