MP240

GENERAL DESCRIPTION

The MP240 operational amplifier is a surface mount

constructed component that provides a cost effective

solution in many industrial applications. The MP240

offers outstanding performance that rivals much more

expensive hybrid components yet has a footprint of

only 4.7 sq in. The MP240 has many optional fea-

tures 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 impor-

tant 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 elec-

trically insulating substrate that can be mounted to a

heat sink.
