OPA454
- Wide Power-Supply Range:
±5 V (10 V) to ±50 V (100 V) - High-Output Load Drive: IO > ±50 mA
- Wide Output Voltage Swing: 1 V to Rails
- Independent Output Disable or Shutdown
- Wide Temperature Range: –40°C to +85°C
- 8-Pin SO Package
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 low-voltage 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.
