Product Summary
The OPA454AIDDAR is a low-cost operational amplifier with ±5V (10V) to ±50V (100V) high voltage (100V) and relatively high current drive (25mA). It is unity-gain stable and has a gain-bandwidth product of 2.5MHz. The OPA454AIDDAR 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 High-V Current Sense 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 OPA454AIDDAR is easy to heatsink over the extended industrial temperature range, －40°C to +85°C.
