GENERAL DESCRIPTION
The AD8666/AD8668 are single supply, rail-to-rail output
amplifiers with low noise performance featuring 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. For lower offset voltage, choose
the
AD8662
(dual).
The combination of offsets, very low input bias currents, and
wide supply range make these amplifiers useful in a wide variety
of cost-sensitive 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, and 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.
The AD8666/AD8668 are specified over the extended industrial
temperature range (-40 to +125C).

ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product 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.
