GENERAL DESCRIPTION
The AD8667 is a dual, rail-to-rail output, single-supply/dual-supply
amplifier that uses Analog Devices, Inc. patented DigiTrim®
trimming technique to achieve low offset voltage, 300 μV over
the common-mode range. The AD8667 features an extended
operating range with supply voltages up to 16 V for low power
operation with an ISY of <325 μA per amplifier over temperature.
The device is designed for low noise at higher voltages: 21 nV/√Hz
at 10 kHz and 23 nV/√Hz at 1 kHz. It also features a low input
bias current of 300 fA and a 10 mA output drive.
The combination of low supply currents, low offsets, very low
input bias currents, and wide supply range makes the AD8667
ideal for a wide variety of low power applications. Systems
utilizing dc-to-low frequency measurements or high impedance
sensors, such as photodiodes, benefit from the low input bias
current, low noise, low offset, and low drive current. The wide
operating voltage range matches today’s high performance
ADCs and DACs. Medical monitoring equipment can take
advantage of the low voltage noise, high input impedance, low
voltage, and low current noise.
The AD8667 is specified over the extended industrial
temperature range of −40°C to +125°C.
