FEATURES SC70 package Very low IB: 1 pA max Single-supply operation: 5 V to 26 V Dual-supply operation: ±2.5 V to ±13 V Rail-to-rail output Low supply current: 630 µA/amp typ Low offset voltage: 500 µV max Unity gain stable No phase reversal APPLICATIONS Photodiode amplifiers ATE Line-powered/battery-powered instrumentation Industrial controls Automotive sensors Precision filters Audio GENERAL DESCRIPTION The AD862x is a precision JFET input amplifier. It features true single-supply operation, low power consumption, and rail-to-rail output. The outputs remain stable with capacitive loads of over 500 pF; the supply current is less than 630 µA/amp. Applications for the AD862x include photodiode transimpedance amplification, ATE reference level drivers, battery management, both line powered and portable instrumentation, and remote sensor signal conditioning including automotive sensors. The AD862x’s ability to swing nearly rail-to-rail at the input and rail-to-rail at the output enables it to be used to buffer CMOS DACs, ASICs, and other wide output swing devices in single-supply systems. The 5 MHz bandwidth and low offset are ideal for precision filters. The AD862x is fully specified over the industrial temperature range. (–40° to +85°) The AD8627 is available in both 5-lead SC70 and 8-lead SOIC surface-mount packages. The SC70 packaged parts are available in tape and reel only. The AD8626 is available in an MSOP package.
