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.
