The OPA512 is a high voltage, very-high currentoperational amplifier designed to drive a wide varietyof resistive and reactive loads. Its complementaryclass A/B output stage provides superior performancein applications requiring freedom from cross-overdistortion. User-set current limit circuitry providesprotection to the amplifier and load in fault conditions.A resistor-programmable voltage-current limitercircuit may be used to further protect the amplifierfrom damaging conditions.The OPA512 employs a laser-trimmed monolithicintegrated circuit to bias the output transistors, providingexcellent low-level signal fidelity and high outputvoltage swing. The reduced internal parts count madepossible with this monolithic IC improves performanceand reliability.This hybrid integrated circuit is housed in a hermeticTO-3 package and all circuitry is electrically-isolatedfrom the case. This allows direct mounting to a chassisor heat sink without cumbersome insulating hardwareand provides optimum heat transfer.
