80W Operational Amplifier

General Description:
The LM12 is a power op amp capable of driving g25V at g10A while operating from g30V supplies. The monolithic IC can deliver 80W of sine wave power into a 4X load with 0.01% distortion. Power bandwidth is 60 kHz. Further, a peak dissipation capability of 800W allows it to handle reactive loads such as transducers, actuators or small motors without derating. The IC delivers g10A output current at any output voltage yet is completely protected against overloads, including shorts to the supplies. The dynamic safe-area protection is provided by instantaneous peak-temperature limiting within the power transistor array The turn-on characteristics are controlled by keeping the output open-circuited until the total supply voltage reaches 14V. The output is also opened as the case temperature exceeds 150§C or as the supply voltage approaches the BVCEO of the output transistors. The IC withstands overvolt ages to 80V.
