DESCRIPTION
The MP38 is a cost-effective high voltage MOSFET
power operational amplifier constructed with surface
mount components on a thermally conductive but elec-
trically 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 ampli-
fiers.
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 opera-
tion. 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 out-
put 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 low-
ers quiescent power dissipation. This is useful in ap-
plications where output crossover distortion is not
important.
