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.
