OPA455中文资料150V、高带宽 6.5MHz、高压摆率 32V/µs 单位增益稳定运算放大器数据手册TI规格书

描述 Description

The OPA455 is a high-voltage (150-V), high current drive (45-mA), unity-gain stable operational amplifier with a gain-bandwidth product of 6.5 MHz and slew rate of 32 V/us. As a result of the amplifier wide output range, this device is an excellent choice for high-voltage piezo driving, avalance photodiode biasing, and high-voltage Howland current pump or voltage output stages.

The OPA455 is internally protected against overtemperature conditions and current overloads. The device is fully specified to perform over a wide power-supply range of ±6 V to ±75 V, or on a single supply of 12 V to 150 V. The status flag is an open-drain output that allows the device to be easily referenced to standard, low-voltage, logic circuitry. This high-voltage operational amplifier provides excellent accuracy and wide output swing, and is free from phase-inversion problems that are often found in similar amplifiers.

The output can be disabled using the enable-disable (E/D) pin. The E/D pin has a common return pin to allow for 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.
