DESCRIPTION
The MP111 operational amplifier is a surface mount constructed component that provides a cost-effec-
tive solution in many industrial 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 compensation. The 500 kHz power bandwidth, 15A con-
tinuous, 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.

Description
Apex test pin, do not connect.
AC coupling to backplate. Connect to signal ground.
Ground. Pins 3 and 32 are not connected on the unit. Connect both pins to system
signal ground.
The positive boost supply rail. Short to +VS if unused. See applicable section.
Compensation capacitor connection. Select value based on Phase Compensation.
See applicable section.
The positive current output. Short to -OUT pins. Connect these pins to the MP111
side of the current limit resistor and the +CL pin. Output current is sourced from
these pins through the current limit resistor and to the load.
The positive supply rail.
The negative supply rail.
The negative current output. Short to +OUT pins. Connect these pins to the MP111
side of the current limit resistor and the +CL pin. Output current sinks to these pins
through the current limit resistor from the load.
The negative boost supply rail. Short to -VS if unused. See applicable section.
Connect to the load side of the current limit resistor and feedback resistor. Current
limit will activate if the voltage across RCL exceeds 0.65V.
Connect to the OUT side of the current limit resistor. Current limit will activate if the
voltage across RCL exceeds 0.65V.
The non-inverting input.
The inverting input.
No Connection.
