DESCRIPTION
The OPA512 is a high voltage, very-high current
operational 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.
A resistor-programmable voltage-current limiter
circuit may be used to further protect the amplifier
from damaging conditions.

APPLICATIONS
q SERVO AMPLIFIER
q MOTOR DRIVER
q SYNCRO EXCITATION
q AUDIO AMPLIFIER
q TEST PIN DRIVER
The OPA512 employs a laser-trimmed monolithic
integrated circuit to bias the output transistors, provid-
ing excellent low-level signal fidelity and high output
voltage swing. The reduced internal parts count made
possible with this monolithic IC improves perfor-
mance and reliability.
This hybrid integrated circuit is housed in a hermetic
TO-3 package and all circuitry is electrically-isolated
from the case. This allows direct mounting to a chassis
or heat sink without cumbersome insulating hardware
and provides optimum heat transfer.
