FEATURES
DESCRIPTION
The OPA454 is a low-cost operational amplifier with
high voltage (100V) and relatively high current drive
(25mA). It is unity-gain stable and has a
gain-bandwidth product of 2.5MHz.
The OPA454 is internally protected against
over-temperature conditions and current overloads. It
is fully specified to perform over a wide power-supply
range of ±5V to ±50V or on a single supply of 10V to
100V. The status flag is an open-drain output that
allows it to be easily referenced to standard
low-voltage logic circuitry. This high-voltage op amp
provides excellent accuracy, wide output swing, and
is free from phase inversion problems that are often
found in similar amplifiers.
The output can be independently disabled using the
Enable/Disable Pin that has its own common return
pin to allow easy interface to low-voltage logic
circuitry. This disable is accomplished without
disturbing the input signal path, not only saving power
but also protecting the load.
Featured in a small exposed metal pad package, the
OPA454 is easy to heatsink over the extended
industrial temperature range, –40°C to +85°C.
