The MP118 is a SMT operational amplifier that pro-
vides a cost effective solution in many industrial ap-
plications. 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 ap-
plications. The MP118 is built on a thermally conduc-
tive 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 perma-
nent damage occurs.
