描述
The ZSSC3281 is a dual path sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. The ZSSC3281 is suitable for bridge and half-bridge sensors, as well as external voltage-source element and single-element sensors (for example, 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 32-bit ARM M3 based 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 ZSSC3281 provides measurement value readouts and programming capabilities via an I2C, SPI, or one-wire interface (OWI). Absolute and ratiometric voltage, current-loop, or interrupt outputs are supported by the ZSSC3281.
