DESCRIPTION

The OPA544 is a high-voltage/high-current operational

amplifier suitable for driving a wide variety of

high power loads. High performance FET op amp

circuitry and high power output stage are combined on

a single monolithic chip.

The OPA544 is protected by internal current limit and

thermal shutdown circuits.

The OPA544 is available in industry-standard

5-lead TO-220 and 5-lead surface-mount power packages.

Its copper tab allows easy mounting to a heat

sink for excellent thermal performance. It is specified

for operation over the extended industrial temperature

range, –40°C to +85°C.
