OPA454 高电压 (100V) 和高电流 (50mA) 运算放大器,G = 1 稳定

The OPA454 is a low-cost operational amplifier withhigh voltage (100V) and relatively high current drive (50mA). 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
