GENERAL DESCRIPTION

The AD8615, AD8616 and AD8618 are single, dual and quad

rail-to-rail input and output single supply amplifiers featuring

very low offset voltage, wide signal bandwidth, and low input

voltage and current noise. These amplifiers use a patented

trimming technique that achieves superior precision without

laser trimming. All are fully specified to operate from +3V to

+5V single supply.

The combination of low offsets, low noise, very low input bias

currents, and high speed make these amplifiers useful in a wide

variety of applications. Filters, integrators, photo-diode

amplifiers 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.

Applications for these amplifiers include Portable and loop-

powered instrumentation, audio amplification for portable

devices, portable phone headsets, bar code scanners, and

multi-pole 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 AD8615, AD8616 and AD8618 are specified over the

extended industrial (-40° to +125°C) temperature range. The

AD8615, single, is available in the tiny 5-lead SOT-23

package. The AD8616, dual, is available in the 8-lead micro-

SOIC and narrow SOIC surface mount packages. The

AD8618, quad, is available in 14-lead TSSOP and narrow 14-

pin SOIC packages.

SOT, MSOP and TSSOP versions are available in tape and

reel only.
