精密低功耗单电源JFET放大器 Precision Low Power Single-Supply JFET Amplifier
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, which includes automotive sensors.
