1. Describe

The OPA454AIDDA device is a low-cost operation Relatively high amplifier with high voltage (100 V) current drive (50mA). It is unity gain stable and has 2.5 MHz gain-bandwidth product. The OPA454 is internally protected overheating conditions and current overload. it Fully specified to perform over a wide supply range Range from ±5 V to ±50 V or on a single 10 V supply to 100 V. The status flag is an open-drain output allows it to be easily referenced to standard low voltage logic circuits. This high pressure operation Amplifier provides excellent accuracy, wide output swing, and no phase reversal issues Commonly found in similar amplifiers. Outputs can be disabled independently using Enable or disable pins that have their own common ground Return pin for easy connection to low voltage logic circuit. This disabling was done without Disturbs the input signal path and not only saves power Also protect the load. Packaged in a small exposed metal pad, The OPA454 is easily extended through the heatsink Industrial temperature range, –40°C to +85°C.

6. Function description

The OPA454AIDDA includes safety features on both device inputs and outputs. On the input side, protection is provided Various failure situations. At the output, current limiting and thermal protection are provided. Performance Benefits include ±50mA output current capability and the ability to swing to within 1V of the supply voltage rail. The enable/disable function provides the ability to turn off the output stage and reduce power consumption when not in use. Status flags indicate fault conditions, available with Enable/disable function to implement fault control loop.

7. Application Information

The OPA454 is a high voltage, high current operational amplifier capable of operating from the following supply voltages Up to ±50 V, or down to ±10 V. Its design and handling make it usable for most op amps cannot be used because of high voltage supply conditions, or due to A very high output voltage swing is required. Output can swing from one volt to several volts The power rails depend on the output current and can be as high as ±50 mA. In addition, the OPA454 With input overvoltage protection, built-in output current limit, thermal protection and output Enable/disable function.
