DUAL LOW-NOISE OPERATIONAL AMPLIFIERS

General Description: The NE5532, NE5532A, SA5532, and SA5532A are high-performance operational amplifiers combining excellent dc and ac characteristics. They feature very low noise, high output-drive capability, high unity-gain and maximum-output-swing bandwidths, low distortion, high slew rate, input-protection diodes, and output short-circuit protection. These operational amplifiers are compensated internally for unity-gain operation. These devices have specified maximum limits for equivalent input noise voltage. Circuit Diagram:


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.

high internal dissipation - 250 wattshigh voltage. high curent - 100V, 30 Ahigh slew rate - 100V/uS4 wire curent limit sensiglow distorsionexternal shutdown controlDescription:
The PA05 is a high voltage MOSFET power operational amplifier that extends the performance limits of power amplifier  in slew rate and power bandwidth, while maintaining high current and power dissipation ratings. The PA05 is a highly flexible amplifier. The shutdown control feature allows the output stage to be turned off for standby operation or load protection during fault conditions. Boost voltage inputs allow the small signal portion of the amplifier to operate at a higher voltage than the high current output stage. The amplifier is then biased to achieve close linear swings to the supply rails at high currents for extra efficient operation.
