GENERAL DESCRIPTION

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.
