DESCRIPTION
The OPA511 is a high voltage, 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 applic ations 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,

roviding 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 hermetically sealed 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.
