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.
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-
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.
