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.
