DESCRIPTION

The MP230 operational amplifier is a surface mount con-

structed component that provides a cost effective solution in

many industrial applications. The MP230 offers outstanding

performance that rivals many much more expensive hybrid

components yet has a footprint of only 4.7 sq in. The MP230

has many optional features such as four-wire current limit sens-

ing, a shutdown 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

crossoverdistortionislessimportantsuchaswhendrivingmotors,

for example. A boost voltage feature biases the output stage for

close linear swings to the supply rail for extra efficient operation.

The MP230 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 MP230 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 MP230 to drive the motor in either direction to a set point

determined by the DAC voltage.
