A signal conditioning integrated circuit includes both signal conditioning circuitry and memory devoted to storing end-user downloadable coefficients. In a preferred embodiment, the integrated circuit is an Application Specific Integrated Circuit (ASIC), and the end-user downloadable coefficients, based upon a mathematical equation pre-selected by the end-user, are pre-stored in the ASIC when a sensor device with which the ASIC is associated is calibrated. This results in a customized and more cost-effective and space-efficient signal-conditioning apparatus with improved functionality over that available in the prior art.

We claim: 1. An apparatus configured as an integrated circuit, comprising:signal-conditioning circuitry configured to perform a coarse-correction on a signal input thereto and to output a coarsely-conditioned signal therefrom, wherein the coarse-correction on the signal compensates the signal for one or more error(s);a storage location storing predetermined coefficients for use in performing a fine-correction on the coarsely-conditioned signal that is output from said signal-conditioning circuitry;a coarsely-conditioned-signal output coupled to said signal-conditioning circuitry and coupleable to an end-user device;a coefficient output coupled to said storage location and coupleable to the end-user device; andwherein when said coarsely-conditioned signal output and said coefficient output are coupled to the end-user device, said end-user device receives the coarsely-conditioned signal from said signal-conditioning circuitry via said coarsely-conditioned signal output and receives said predetermined coefficients from said storage location via said coefficient output to perform the fine-correction.
