DESCRIPTION
The MP108 operational amplifier is a surface mount constructed
component that provides a cost effective solution in many indus-
trial applications. The MP108 offers outstanding performance
that rivals much more expensive hybrid components yet has a
footprint of only 4 sq in. The MP108 has many optional features
such as four-wire current limit sensing and external compensation.
The 300 kHz power bandwidth and 10 amp output of the MP108
makes it a good choice for piezo transducer drive applications.
The MP108 is built on a thermally conductive but electrically
insulating substrate that can be mounted to a heat sink.
