DESCRIPTION
The MP240 operational amplifier is a surface mount con-
structed component that provides a cost effective solution in
many industrial applications. The MP240 offers outstanding
performance that rivals much more expensive hybrid compo-
nents yet has a footprint of only 4.7 sq in. The MP240 has many
optional features such as four-wire current limit sensing, a shut-
down control and external compensation. In addition, the class
A/B output stage biasing can be turned off for lower quiescent
current with class C operation in applications where crossover
distortion is less important such as when driving motors, for
example. A boost voltage feature biases the output stage for
close linear swings to the supply rail for extra efficient operation.
The MP240 is built on a thermally conductive but electrically
insulating substrate that can be mounted to a heat sink.

TYPICAL APPLICATION
MOTOR POSITION CONTROL
The MOSFET output stage of the MP240 provides superior
SOA performance compared to bipolar output stages where
secondary breakdown is a concern. The extended SOA is
ideal in motor drive applications where the back EMF of the
motor may impose simultaneously both high voltage and high
current across the output stage transistors. In the figure above
a mechanical to electrical feedback position converter allows
the MP240 to drive the motor in either direction to a set point
determined by the DAC voltage.
