GENERAL DESCRIPTION
The AD8661 is a single, rail-to-rail output, single-supply
amplifier that uses Analog Devices’ patented DigiTrim®
trimming technique to achieve a low offset voltage. The
AD8661 features an extended operating range with supply
voltages up to 16 V. It also features 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 a wide supply range makes this amplifier useful in a wide
variety of applications normally associated with much higher
priced JFET amplifiers. Systems using high impedance sensors,
such as photodiodes, benefit from the combination of low input
bias current, low noise, low offset, and wide 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, and wide bandwidth.
