The OPA2544 is a dual high-voltage/high-current operational amplifier. We can use it for driving a wide variety of high power loads. 2A output current is provided by this device and power supply range extends to -35V.

Two high performance FET op amps with high power output stages are integrated in OPA2544 on a single monolithic chip. The amplifier and load are protected from damage by internal current limit and thermal shutdown.

The OPA2544 is specified for the -40′C to 85′C temperature range and this device is avaiable in a 11-lead plactic packages. Here’s the circuit diagram:
