tional 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 pack-
ages. 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.

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 degrada-
tion 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.
