GENERAL DESCRIPTION The 5 MHz bandwidth and low offset are ideal for precision filters. The AD862x is a precision JFET input amplifier. It features true single-supply operation, low power consumption, and The AD862x is fully specified over the industrial temperature rail-to-rail output. The outputs remain stable with capacitive range. (40C to +85C). The AD8627 is available in both loads of over 500 pF the supply current is less than 630 A/amp. 5-lead SC70 and 8-lead SOIC surface-mount packages (SC70 Applications for the AD862x include photodiode transimpedance packaged parts are available in tape and reel only). The AD8626 amplification, ATE reference level drivers, battery management, is available in MSOP and SOIC packages, while the AD8625 is both line powered and portable instrumentation, and remote available in TSSOP and SOIC packages. sensor signal conditioning, which includes automotive sensors. The AD862xs 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.
