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

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.
