GENERAL DESCRIPTION
The AD8627 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. Applications for the AD8627 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 AD8627'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 singlesupply systems. The 5 MHz bandwidth and low offset are ideal for precision filters. The AD8627 is fully specified over the extended industrial (40°C to +125°C) temperature range and 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.

CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the AD8627 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
