GENERAL DESCRIPTION
The AD866x family 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 AD8661/AD8662/AD8664 family
.
The combination of low 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 using 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 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 AD866x family is specified over the extended industrial
temperature range (-40C to +125C).
