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.
