Introduction

MP38 is a cost-effective high-voltage MOSFET power operational amplifier built with surface-mount components on a thermally conductive yet electrically isolated substrate. Despite its low cost, the MP38 offers many features and performance specifications found only in more expensive hybrid power amplifiers. The metal substrate allows the MP38 to dissipate up to 125W of power, with a supply voltage range of up to ±100V (200V total). An optional boost voltage input allows the small-signal section of the amplifier to operate at a higher supply voltage than the high-current output stage. The amplifier is then biased to achieve near-rail linear swing at high currents, enabling more efficient operation. External compensation allows performance to be tailored to user requirements. Four-wire sensing technology enables current limiting without regard to internal or external milliohm-level parasitic resistance in the output lines. An Iq pin is provided to shut down the quiescent current of the output stage, at which point the output stage operates in Class C, reducing quiescent power dissipation. This is useful in applications where output crossover distortion is not critical.
