The AD8661, AD8662 and AD8664 are single, dual and quad rail-to-rail output single supply amplifiers that use Analog Devices’ patented DigiTrim® trimming technique to achieve low offset voltage. The AD8661 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 AD8661, AD8662 and AD8664 are specified over the extended industrial (-40° to +125°C) temperature range. The AD8661, single, is available in the tiny 8-lead LFCSP (MO-220) 3mm x 3mm and 8-lead SOIC package. The AD8662, dual, is available in the 8-lead micro-SOIC and narrow SOIC surface mount packages. The AD8664, quad, is available in 14-lead TSSOP and narrow 14-pin SOIC packages. LFCSP, MSOP and TSSOP versions are available in tape and reel only.
