ZSSC3281BI3R is an advanced dual channel ARM based resistive sensor signal conditioner IC. This is highly accurate amplification, digitization, and sensor-specific correction of sensor signals. This suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors powered by an on-chip current source. Digital compensation of the sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via a 32-bit ARM M3 based math core running a correction algorithm with calibration coefficients stored in non-volatile, reprogrammable memory. The programmable, integrated sensor frontend allows optimally applying various sensors for a broad range of applications. This provides measurement value readouts and programming capabilities via an I2C, SPI, or one-wire interface. Absolute and radiometric voltage, current-loop, or interrupt outputs are supported by the ZSSC3281.
