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.
Tab is connected
to V– supply.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet its
published specifications.
