GENERAL DESCRIPTION

The AD866x are rail-to-rail output amplifiers that use the

Analog Devices, Inc., patented DigiTrim® trimming technique

to achieve low offset voltage. The AD866x feature an extended

operating range with supply voltages up to 16 V. They also

feature low input bias current, low input offset voltage, and

low current noise.

frequency data converters. The low bias current drift is well-

suited for precision I-to-V converters. The combination of

precision offset, offset drift, and low noise also make the op

amps ideal for gain, dc offset adjust, and active filter in both

instrumentation and medical applications. These low power

op amps can be used in IR thermometers, pH and ORP instru-

ments, pressure transducer front ends, and other sensor signal

conditioning circuits that are used in remote or wireless

applications.

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 ampli-

fiers. 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 AD8663/AD8667/AD8669 are specified over the extended

industrial temperature range of −40°C to +1±5°C. The single

AD8663 is available in a narrow 8-lead SOIC package and a very

thin, 8-lead LFCSP. The dual AD8667 is available in a narrow

8-lead SOIC package and an 8-lead MSOP. The quad AD8669

is available in a 14-lead SOIC and 14-lead small TSSOP.

The ability to operate the device for single (5 V to 16 V) or dual

supplies (±±.5 V to ±8 V) supports many applications. The rail-

to-rail outputs provide increased dynamic range to drive low
