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.
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 ability to operate the device for single (5 V to 16 V) or dual
supplies (±2.5 V to ±8 V) supports many applications. The rail-
to-rail outputs provide increased dynamic range to drive low

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 AD8663/AD8667/AD8669 are specified over the extended
industrial temperature range of −40°C to +125°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.
