GENERAL DESCRIPTION
The AD8643-EP 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 digital-to-analog
converters (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 AD8643-EP is suitable for applications using multichannel
boards that require low power to manage heat. Other applications
include photodiodes and battery management.
The AD8643-EP is fully specified over the military temperature
range of 55°C to +125°C. This device is available in a 14-lead SOIC.
Additional applications information is available in the AD8643
data sheet.
