MP111 RoHS Power Operational Amplifier COMPLIANT FEATURES Low Cost High Voltage - 100V High Output Current- 50A Pulse Output, 15A Continuous 170W Dissipation Capability 130V/s Slew Rate 500 kHz Power Bandwidth APPLICATIONS Inkjet Printer Head Drive Piezo Transducer Drive Industrial Instrumentation Reflectometers Ultra-sound Transducer Drive 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.
