ZSSC3240 Overview
The ZSSC3240 is a sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of resistive sensor signals. The ZSSC3240 is suitable for bridge and half-bridge sensors, as well as external voltagesource element and single-element sensors (e.g., Pt100 and external temperature sensor diodes) powered by an on-chip current source. Digital pensation of the sensor offset, sensitivity, temperature drift, and non-linearity is acplished via a 26-bit math core running a correction algorithm with calibration coefficients stored in a non-volatile, reprogrammable memory. The programmable, integrated sensor front-end allows optimally applying various sensors for a broad range of
