OPA818 Overview
The OPA818 is a depensated, voltage-feedback operational amplifier for high-speed and wide dynamic range applications. OPA818 has a low-noise junction gate field-effect transistor (JFET) input stage that bines high gain-bandwidth with a wide supply range from 6 V to 13 V. The fast slew rate of 1400 V/µs provides high large-signal bandwidth and low distortion.
