The OPA462 is a high voltage (180 V) and high current drive (45 mA) operational amplifier. The device is unity-gain stable and has a gain-bandwidth product of 6.5 MHz.

The OPA462 is internally protected against over-temperature conditions and current overloads. The device is fully specified to perform over a wide power-supply range of ±6 V to ±90 V, or on a single supply of 12 V to 180 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.

Featured in a small exposed-metal pad package, the OPA462 dissipates heat over the industrial temperature range of –40°C to +85°C.
