AD8659ARZ (ANALOG DEVICES)

The AD8659ARZ is a micropower precision quad CMOS Operational Amplifier with rail-to-rail input/output. It is optimized for low power and wide operating supply voltage range applications. The AD8659 operate from 2.7 to 18V with a typical quiescent supply current of 18µA. The device uses the patented DigiTrim® trimming technique, which achieves low offset voltage. The AD8659 also have high immunity to electromagnetic interference. The combination of low supply current, low offset voltage, very low input bias current, wide supply range and rail-to-rail input and output make the AD8659 ideal for current monitoring in process. The combination of precision specifications makes these devices ideal for DC gain and buffering of sensor front ends or high impedance input sources in wireless or remote sensors or transmitters.
