The AD8643-EP is a low power, precision JFET input amplifier The AD8643-EP is suitable for applications using multichannel featuring extremely low input bias current and rail-to-rail output. boards that require low power to manage heat. Other applications The ability to swing nearly rail-to-rail at the input and rail-to-rail at include photodiodes and battery management. the output enables designers to buffer CMOS digital-to-analog The AD8643-EP is fully specified over the military temperature converters (DACs), ASICs, and other wide output swing devices range of −55°C to +125°C. This device is available in a 14-lead SOIC. in single-supply systems. The outputs remain stable with capacitive loads of more than 500 pF. Additional applications information is available in the AD8643 data sheet.
