Abstract

A sensor includes one or more sensor transducers coupled with a signal conditioning IC incorporating signal conditioning circuitry and memory devoted to storing end-user downloadable coefficients. In a preferred embodiment, the IC is an ASIC and the end-user downloadable coefficients are pre-selected by the end-user based on its needs, and the coefficients are pre-stored in the ASIC when the sensor is calibrated. This results in a more cost-effective and space-efficient sensor device with improved functionality over that available in the prior art.
