SBOSA16 October 2020 OPA455
The OPA455 is a high-voltage, high-current operational amplifier capable of operating with supply voltages as high as ±75 V (150 V), or as low as ±6 V (12 V). The high-voltage process and design of the OPA455 allows the device to be used in applications where most operational amplifiers cannot be applied, such as high-voltage power-supply conditions, or when there is a need for very a high-output voltage swing. The output is capable of delivering up to ±45 mA output current, or swinging within a few volts of the supply rails at moderate current levels. The OPA455 features input overvoltage protection, output current limiting, thermal protection, a status flag, and enable-disable capability.
