GENERAL DESCRIPTION
The AD8661/AD8662/AD86641 are rail-to-rail output, singlesupply amplifiers that use the Analog Devices, Inc., patented
DigiTrim® trimming technique to achieve low offset voltage.
The AD8661/AD8662/AD8664 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
analog-to-digital converters (ADCs) and digital-to-analog
1
converters (DACs). Audio applications and medical monitoring
equipment can take advantage of the high input impedance, low
voltage, low 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
package is specified over the extended industrial temperature
range of −40°C to +125°C. The AD8661 LFCSP 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.
