MP118 Power Operational Amplifier RoHS COMPLIANT FEATURES • • • • • • High Voltage - 200V High Output Current 10A continuous 100W Dissipation Capability 140 kHz Power Bandwidth Temperature Monitor Integrated Shut-Down APPLICATIONS • • • • • Ink Jet Printer Head Drive Piezo Transducer Drive Industrial Instrumentation Reflectometers Ultra-Sound Transducer Drive DESCRIPTION The MP118 is a SMT operational amplifier that provides a cost effective solution in many industrial applications. The MP118 offers outstanding performance that rivals much more expensive hybrid components, but yet has a footprint of only ≈26cm2 (4 in2). The 140 kHz power bandwidth and 10A output of the MP118 makes it a good choice for piezo transducer drive applications. The MP118 is built on a thermally conductive but electrically insulating substrate that can be mounted to a heat sink. MP118 is based on the MP108 design, but offers lower quiescent current consumption and new features for enhanced system protection. The newly introduced over-current protection and temperature monitoring circuitry will shut-down the system before any permanent damage occurs.
