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 minimizing their output loading effects. Laser trimming of the input circuitry yields low input offset voltage and drift. The OPA445 is available in standard pin-out TO-99, DIP-8, and SO-8 surface-mount packages. It is fully specified from –25°C to +85°C and operates from –55°C to +125°C. A SPICE macromodel is available for design analysis.
