3 Description
The OPA454 device is a low-cost operational
amplifier with high voltage (100 V) and relatively high
current drive (50 mA). It is unity-gain stable and has a
gain-bandwidth product of 2.5 MHz.
The OPA454 is internally protected against
overtemperature conditions and current overloads. It
is fully specified to perform over a wide power-supply
range of ±5 V to ±50 V or on a single supply of 10 V
to 100 V. The status flag is an open-drain output that
allows it to be easily referenced to standard lowvoltage
logic circuitry. This high-voltage operational
amplifier 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 or 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.
