General Description

The AD8641/AD8642/AD8643 are low power, precision JFET input amplifiers 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 complementary metal-oxide semiconductor digital-to-analog converters (CMOS DACs), ASICs, and other wide output swing devices in single-supply systems.

The outputs remain stable with capacitive loads of
