Data Sheet Low Power, Rail-to-Rail Output, Precision JFET Amplifiers AD864/AD8642/AD8643 FEATURES Low supply current: 25 μa max Very low input bias current: pa max Low offset voltage: 75 μv max Single-supply operation: 5 V to 26 V Dual-supply operation: ±2.5 V to ±3 V Rail-to-rail output Unity-gain stable No phase reversal SC7 package APPLICATIONS Line-/battery-powered instruments Photodiode amplifiers Precision current sensing Medical instrumentation Industrial controls Precision filters Portable audio ATE GENERAL DESCRIPTION The AD864/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 CMOS DACs, ASICs, and other wide output swing devices in single-supply systems. The outputs remain stable with capacitive loads of more than 5 pf. The AD864/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 AD864/AD8642/AD8643 are fully specified over the extended industrial temperature range of 4 C to +25 C. The AD864 is available in 5-lead SC7 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 4-lead SOIC and 6-lead, 3 mm 3 mm, LFCSP lead-free packages.

Exposure to absolute maximum rating conditions for extended periods may affect device reliability. AD864/AD8642/AD8643 THERMAL RESISTANCE θja is specified for the worst-case conditions, that is, a device soldered in a circuit board for surface-mount packages. This was measured using a standard 4-layer board. For the LFCSP package, solder the exposed pad to a copper plane, which should be connected to V+. Table 4.
