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 high-voltage 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 pinout TO-99, DIP-8, and SO-8 surface-mount packages as well as an SO-8 PowerPAD package for reducing junction temperature. 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 (from www.ti.com).
