The ZSSC3241 is a sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of resistive sensor signals. The ZSSC3241 provides best-in-class sensor-element adaptability, and it is suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors in multiple configurations. Digital compensation of the sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via a 26-bit math core running a correction algorithm with calibration coefficients stored in a non-volatile, reprogrammable memory. A second, separate compensation for gain and offset, and digital-output independent analog-output correction is supported for optimum adaptability of dual-domain (analog and digital) sensor solutions. The programmable, integrated sensor front-end allows optimally applying various sensors for a broad range of applications.
