GENERAL DESCRIPTIONThe AD8605, AD8606, and AD8608 are single, dual, and quad
rail-to-rail input and output, single-supply amplifiers that feature
very low offset voltage, low input voltage and current noise, and
wide signal bandwidth. They use Analog Devices’ patented
DigiTrim® trimming technique, which achieves superior precision
without laser trimming.
The combination of low offsets, low noise, very low input bias
currents, and high speed makes 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. Audio and other ac
applications benefit from the wide bandwidth and low distortion.
Applications for these amplifiers include optical control loops,
portable and loop-powered instrumentation, and audio amplifica-
tion for portable devices.
The AD8605, AD8606, and AD8608 are specified over the
extended industrial (–40°C to +125°C) temperature range. The
AD8605 single is available in the tiny 5-lead SOT-23 package. The
AD8606 dual is available in an 8-lead MSOP and a narrow SOIC
surface-mount package. The AD8608 quad is available in a 14-lead
TSSOP and a narrow 14-lead SOIC package. SOT, MSOP, and
TSSOP versions are available in tape and reel only.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect device reliability.
*θJA is specified for worst-case conditions, i.e., θJA is specified for device in
socket for PDIP packages; θJA is specified for device soldered onto a circuit
board for surface-mount packages.
CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD8605/AD8606/AD8608 features proprietary ESD protection circuitry, permanent damage
may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
