Name: OPA541 High Voltage High Current Power Amplifier; Size: 96mm*64mm*41mm (length, width, height); Supply voltage range: ±10V~±40V The OPA541 module is a power operational amplifier capable of operating with a power supply up to 40V and providing continuous output current up to 5A. The internal current limiting circuit can be controlled by the user using a single external resistor to protect the amplifier and load from fault conditions.
