AD8663/AD8667/AD8669 is a low noise, high precision, 16 V, CMOS, Rail-to-Rail operational amplifier from Analog Devices.
The AD866x series are rail-to-rail output amplifiers utilizing the patented DigiTrim® trimming technique to achieve low offset voltage. They feature an extended operating range with supply voltages up to 16 V, along with very low input bias current and low current noise.
These devices support single-supply operation from 5 V to 16 V or dual supplies from +2.5 V to +8 V. The combination of precision offset, drift characteristics, and wide bandwidth makes them suitable for sensor front ends, transimpedance amplifiers, electrometer applications, and medical diagnostic instruments.
