DESCRIPTION
The MP38 is a cost-effective high voltage MOSFET power operational amplifier constructed with surface mount components on a thermally conductive but electrically isolated substrate. While the cost is low the MP38 offers many of the same features and performance specifications found in much more expensive hybrid power amplifiers. The metal substrate allows the MP38 to dissipate power up to 125 watts and its power supply voltages can range up to +/- 100 Volts (200V total). Optional boost voltage inputs allow the small signal portion of the amplifier to operate at higher supply voltages than the high current output stage. The amplifier is then biased to achieve close linear swings to the supply rails at high current for extra efficient operation. External compensation tailors performance to the user needs. A four-wire sense technique allows current limiting without the need to consider internal or external mili-ohm parasitic resistance in the output line. An Iq pin is available which can be used to shut off the quiescent current in the output stage. The output stage then operates class C and lowers quiescent power dissipation. This is useful in applications where output crossover distortion is not important.
TYPICAL APPLICATION
Ref: Application Note 25
The high power bandwidth and high voltage output of the MP38 allows driving ultra-sonic transducers via a resonant circuit including the transducer and a matching transformer. The load circuit appears resistive to the MP38.

Unless otherwise noted: TC = 25°C, CC = 100, RC = 470pF. DC input specifications are ± value given. Power supply voltage is typical rating. ±VB = ±VS. Long term operation at the maximum junction temperature will result in reduced product life. Derate internal power dissipation to achieve high MTTF. For guidance, refer to the heatsink data sheet. Rating applies if the output current alternates between both output transistors at a rate faster than 60 Hz. The MP38 must be used with a heat sink or the quiescent power may drive the unit to junction temperatures higher than 175°C.
CAUTION
The MP38 is constructed from MOSFET transistors. ESD handling procedures must be observed.
