GENERAL DESCRIPTION
The AD8663 is single rail-to-rail output single/dual supply
amplifiers that use Analog Devices’ patented DigiTrim®
trimming technique to achieve low offset voltage, 300μV over
the common mode range. The AD8663 family features an
extended operating range with supply voltage up to 16V for low
power operation with ISY of < 325μA over the extended
industrial temperature. These devices are designed for low
noise at higher voltages, 21nV/√Hz at 10kHz and 23 nV/√Hz at
1 kHz. They also feature low input bias currents of 300fA 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 AD8663 is specified over the extended industrial (-40ºC to
+125ºC) temperature range.
