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 more than 500 pF.

The

AD8641/AD8642/AD8643

are suitable for applications

utilizing multichannel boards that require low power to manage

heat. Other applications include photodiodes, ATE reference

level drivers, battery management, and industrial controls.

The

AD8641/AD8642/AD8643

are fully specified over the

extended industrial temperature range of −40°C to +125°C. The

AD8641

is available in 5-lead SC70 and 8-lead SOIC lead-free

packages. The

AD8642

is available in 8-lead MSOP and 8-lead

SOIC lead-free packages. The

AD8643

is available in 14-lead

SOIC and 16-lead, 3 mm × 3 mm, LFCSP lead-free packages.
