<div class="htmlview paragraph">Until now, environmental and cost concerns have inhibited widespread application of piezoresistive pressure transducers in many applications. The monolithic silicon pressure sensor, unlike a conventional I C, must interface with the environment.</div> <div class="htmlview paragraph">The circuit side of the sensor chip is protected from the environment in the integrated pressure transducer (IPT).</div> <div class="htmlview paragraph">The entire circuit, including high level amplification and temperature compensation<i>, </i> is placed on a chip only 0.1″ square. It has built-in trim capability via thin film resistors and is contained in a package de signed for low cost processing.</div>
