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 V 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 A 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
