GENERAL DESCRIPTION

The AD8661/AD8662/AD8664 are rail-to-rail output, single-

supply amplifiers that use the Analog Devices, Inc., patented

DigiTrim® trimming technique to achieve low offset voltage.

The AD866x series features extended operating ranges, with

supply voltages up to 16 V. It also features low input bias

current, wide signal bandwidth, and low input voltage and

current noise.

The combination of low offset, very low input bias current, and

a wide supply range makes these amplifiers useful in a wide

variety of applications usually associated with 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 meets the demands of 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.

The single AD8661 is available in a narrow 8-lead SOIC

package and a very thin, dual lead, 8-lead LFCSP. The AD8661

SOIC_N package is specified over the extended industrial

temperature range of −40°C to +125°C. The AD8661

LFCSP_VD is specified over the industrial temperature range

of −40°C to +85°C. The AD8662 is available in a narrow 8-lead

SOIC package and an 8-lead MSOP, both specified over the

extended industrial temperature range of −40°C to +125°C. The

AD8664 is available in a narrow 14-lead SOIC package and a

14-lead TSSOP, both with an extended industrial temperature

range of −40°C to +125°C.
