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.
