AD8663

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, 300V 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 < 325A 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 (-40 to +125) temperature range.
