The OPA2544 is a dual high-voltage/high-current operational amplifier suitable for driving a wide variety of high power loads. It provides 2A output current and power supply voltage range extends to ±35V.
The OPA2544 integrates two high performance FET op amps with high power output stages on a single monolithic chip. Internal current limit and thermal shutdown protect the amplifier and load from damage.
The OPA2544 is available in a hermetic 8-pin metal TO-3, and 11-lead plastic packages. Models are available in -40°C to +85°C, and -55°C to +125°C temperature ranges.
