GENERAL DESCRIPTION
The AD8669 is a rail-to-rail output, single-supply amplifier that
uses the Analog Devices, Inc., patented DigiTrim® trimming
technique to achieve low offset voltage. The AD8669 features an
extended operating range, with supply voltages up to 16 V. It
also features low input bias current, low input 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 amplifiers. Systems using high impedance sensors, such as

(R-14)
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 quad AD8669 is available in a narrow 14-lead SOIC package
and 14-lead TSSOP. The AD8669 is specified over the extended
industrial temperature range of −40°C to +125°C.
