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 perfor-

mance 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, 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 pack-

ages. The AD8604, quad, is available in 14-lead TSSOP and

narrow SOIC packages.

SOT, µSOIC, and TSSOP versions are available in tape and

reel only.
