AD8664:  16 V Precision, CMOS Rail-to-Rail Quad Op Amp

The AD8664 is a quad rail-to-rail output single supply amplifiers that use Analog Devices’ patented DigiTrim® trimming technique to achieve low offset voltage. The AD8664 family features 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.

The combination of low offsets, very low input bias currents, and wide supply range make these amplifiers useful in a wide variety of applications normally associated with much higher priced JFET amplifiers. Systems utilizing high impedance sensors, such as photo-diodes benefit from the combination of low input bias current, low noise, low offset and bandwidth. The wide operating voltage range matches today’s 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 AD8664 is specified over the extended industrial (-40° to +125°C) temperature range. The AD8664, quad, is available in the 14-lead SOIC and TSSOP surface mount packages.
