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).
