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 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, 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 a tiny, 5-lead SOT-23 package. The
AD8602, dual, is available in 8-lead MSOP and 8-lead, narrow
SOIC surface-mount packages. The AD8604, quad, is available
in 14-lead TSSOP, 14-lead SOIC, and 16-lead QSOP packages.
