DESCRIPTION
The OPA511 is a high voltage, high current opera-
tional amplifier designed to drive a wide variety of
resistive and reactive loads. Its complementary class
A/B output stage provides superior performance in
applications requiring freedom from cross-over
distortion. User-set current limit circuitry provides
protection to the amplifier and load in fault conditions.
The OPA511 employs a laser-trimmed monolithic
integrated circuit to bias the output transistors,
providing excellent low-level signal fidelity and
high output voltage swing. The reduced internal parts
count made possible with this bias IC improves
performance and reliability.
This hybrid integrated circuit is housed in a hermeti-
cally sealed TO-3 package and all circuitry is electri-
cally isolated from the case. This allows direct mount-
ing to a chassis or heat sink without cumbersome
insulating hardware and provides optimum heat trans-
fer.
