Product Overview

The MP118FD is a low cost, low quiescent current power operational amplifier that integrates sev-

eral new layers of onboard circuit protection including over current shut down. Featuring a surface

mount, open frame packaging design with a footprint measuring just 26cm2 (4in2), the MP118FD

exhibits just 26mA of quiescent current and is capable of 100W of internal power dissipation.

Based on a sibling amplifier the MP108FD, the MP118FD introduces several new safe guards includ-

ing temperature monitoring, temperature shut down and external shut down. The over current limit

function available with the MP108FD has been replaced by an over current shut down functionality

for better short circuit and system protection. This will protect the power amplifier from over stress

due to excessive current and unsafe power dissipation. Onboard temperature monitoring circuitry,

also new, enables the MP118FD to shut down the system before any permanent damage can occur.

In terms of electrical performance, the MP118FD does not disappoint. The product is compatible

with supplies up to 200V, is capable of 10A of continuous output current, or 12A PEAK, and has a

power bandwidth of 140kHz. This combination of current, voltage and banwidth makes the device

an ideal solution for piezo transducer drive applications.

Typical Application

With 140kHz power bandwidth and 10A of continuous output current, the MP118FD is a targeted

choice for piezo drive applications, specifically inkjet print heads. Other applications include indus-

trial instrumentation, manufacturing automation, reflectometers and ultra-sound transducer drives.
