DESCRIPTION
The OPA544 is a high-voltage/high-current opera-
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, 鈥?0擄C to +85擄C.
