GENERAL DESCRIPTION
The AD8601, AD8602, and AD8604 are single, dual, and quad
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 on a 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
applications. Filters, integrators, diode amplifiers, shunt current
sensors, and high impedance sensors all benefit from the combi-
nation 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 per-
formance 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, cellular PA controls, 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, AD8602, and AD8604 are specified over the
extended industrial (–40°C to +125°C) temperature range. The
AD8601, single, is available in the tiny 5-lead SOT-23 package.
The AD8602, dual, is available in 8-lead MSOP and narrow
SOIC surface-mount packages. The AD8604, quad, is available
in 14-lead TSSOP and narrow SOIC packages.
SOT, MSOP, and TSSOP versions are available in tape and
reel only.
