The OPA445 is a monolithic operational amplifier capable of operation from power supplies up to 45V and output currents of 15mA. It is useful in a wide variety of applications requiring high output voltage or large common-mode voltage swings. The OPA445's high slew rate provides wide powerbandwidth response, which is often required for highvoltage applications. FET input circuitry allows the use of high-impedance feedback networks, thus mini-
