Detailed Description

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 voltage-source ele­ment and single-element sensors (e.g., Pt100 and external temper­ature sensor diodes) powered by an on-chip current source. 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. The programmable, integrated sensor front-end allows optimally applying various sensors for a broad range of applications. The ZSSC3240 provides measurement value readouts and programming capabilities via an I2C, SPI, or one-wire interface (OWI). Three different operation modes allow optimal development of digital, digital-analog, and analog-output smart sensor modules including wake-up on request, continuous-on/fast‑response, and automatic/cyclic sensor measurement operations. Absolute and ratiometric voltage, current-loop, or interrupt analog outputs are supported by the ZSSC3240. The analog output options and digital interface options (for calibration and/or a digital application inter­face) can be combined.
