AD8641

The AD8641 is a low power, precision JFET input amplifier featuring extremely low input bias current and rail-to-rail output. The ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables designers to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems. The outputs remain stable with capacitive loads of more than 500 pF.

The AD8641 is suitable for applications utilizing multichannel boards that require low power to manage heat. Other applica-tions include photodiodes, ATE reference level drivers, battery management, and industrial controls.

The AD8641 is fully specified over the extended industrial temperature range of 40° to +125°C. The AD8641 is available in 5-lead SC70 and 8-lead SOIC lead-free packages.
