DESCRIPTION
The MP38 is a cost-effective high voltage MOSFET power
operational amplifier constructed with surface mount com-
ponents 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.
