The OPA445 is a monolithic operaTIonal amplifiercapable of operaTIon from power supplies up to ±45Vand output currents of 15mA. It is useful in a widevariety of applicaTIons requiring high output voltageor large common-mode voltage swings.The OPA445’s high slew rate provides wide powerbandwidthresponse, which is often required for highvoltageapplicaTIons. FET input circuitry allows theuse of high-impedance feedback networks, thus minimizingtheir output loading effects. Laser trimming ofthe input circuitry yields low input offset voltage anddrift.The OPA445 is available in standard pin-out TO-99,DIP-8, and SO-8 surface-mount packages. It is fullyspecified from –25°C to +85°C and operates from–55°C to +125°C. A SPICE macromodel is availablefor design analysis.
