GENERAL DESCRIPTION
The AD8667 is a dual rail-to-rail output single supply and dual
supply amplifiers that use Analog Devices’ patented
DigiTrim® trimming technique to achieve low offset voltage,
300μV over the common mode range. The AD8667 family
features an extended operating range with supply voltages up
to 16 V for low power operation with I_SY of < 325 μΑ over the
extended industrial temperature. These devices are designed
for low noise at higher voltages, 20 nV/√Hz at 10 kHz and 23
nV/√Hz at 1 kHz. They also feature low input bias currents of
1pA and 10mA output drive.
The combination of low supply currents, low offsets, very low
input bias currents, and wide supply range make these
amplifiers useful in a wide variety of low power applications.
Systems utilizing DC to low frequency measurements, or high
impedance sensors, such as photo-diodes benefit from the
combination of low input bias current, low noise, low offset
and drive current. The wide operating voltage range matches
today’s high performance ADCs and DACs. Medical
monitoring equipment can take advantage of the low voltage
noise, high input impedance, low voltage and current noise,.
The AD8667 is specified over the extended industrial (-40° to
+125°C) temperature range.
