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.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
