DESCRIPTION

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.

mizing 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.

The OPA445’s high slew rate provides wide power-

bandwidth response, which is often required for high-

voltage applications. FET input circuitry allows the

use of high-impedance feedback networks, thus mini-
