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.
