GENERAL DESCRIPTION
The AD8661, AD8662 and AD8664 are single, dual and quad
rail-to-rail output single supply amplifiers that use Analog
Devices’ patented DigiTrim® trimming technique to achieve
low offset voltage. The AD8661 family features an extended
operating range with supply voltages up to 16 V. They also
feature low input bias currents, wide signal bandwidth, and low
input voltage and current noise.
AD8664
AD8661
The combination of low offsets, very low input bias currents,
and wide supply range make these amplifiers useful in a wide
variety of applications normally associated with much higher
priced JFET amplifiers. Systems utilizing high impedance
sensors, such as photo-diodes benefit from the combination of
low input bias current, low noise, low offset and bandwidth.
The wide operating voltage range matches today’s high
performance ADCs and DACs. Audio applications and
medical monitoring equipment can take advantage of the high
input impedance, low voltage and current noise, wide
bandwidth and the lack of “popcorn” noise (found in many
other low input bias current amplifiers).

AD8664
The AD8661, AD8662 and AD8664 are specified over the
extended industrial (-40° to +125°C) temperature range. The
AD8661, single, is available in the tiny 8-lead LFCSP (MO-
220) 3mm x 3mm and 8-lead SOIC package. The AD8662,
dual, is available in the 8-lead micro-SOIC and narrow SOIC
surface mount packages. The AD8664, quad, is available in
14-lead TSSOP and narrow 14-pin SOIC packages.
LFCSP, MSOP and TSSOP versions are available in tape and
reel only.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 1500 V
readily accumulate on the human body and test equipment and can discharge without
detection. Although this device 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.
