GENERAL DESCRIPTION
The AD8616/AD8618 are dual/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. The parts use a patented trimming technique that
achieves superior precision without laser trimming. The
AD8616/AD8618 are fully specified to operate from 2.7 V to
5 V single supplies.
The combination of 20 MHz bandwidth, low offset, low noise,
and very low input bias current make these amplifiers useful in
a wide variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from the
combination of performance features. AC applications benefit
from the wide bandwidth and low distortion. The AD8616/
AD8618 offer the highest output drive capability of the
Rev. A

DigiTrim^TM family, which is excellent for audio line drivers and
other low impedance applications.
Applications for the parts include portable and low powered
instrumentation, audio amplification for portable devices,
portable phone headsets, bar code scanners, 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 AD8616/AD8618 are specified over the extended industrial
(–40°C to +125°C) temperature range. The AD8616 is available
in 8-lead MSOP and narrow SOIC surface mount packages; the
MSOP version is available in tape and reel only. The AD8618 is
available in 14-lead SOIC and 14-lead TSSOP packages.
