DESCRIPTION
The MP111 operational amplifier is a surface mount constructed
component that provides a cost-effective solution in many indus-
trial applications. The MP111 offers outstanding performance
that rivals much more expensive hybrid components yet has a
footprint of only 4 sq in. The MP111 has many optional features
such as four-wire current limit sensing and external compensa-
tion. The 500 kHz power bandwidth and 15 amp continuous
and 50A pulse output of the MP111 makes it a good choice
for piezo transducer drive applications. The MP111 is built on
a thermally conductive but electrically insulating substrate that
can be mounted to a heat sink.

INKJET NOZZLE DRIVE
The MP111's fast slew rate and wide power bandwith make it
an ideal nozzle driver for industrial inkjet printers. The 50 amp
pulse output capability can drive hundreds of inkjet nozzles
simultaneously.
