Description
The ZSSC3286 is a dual path sensor signal conditioning IC (SSC) for highly accurate amplification, digitization, and sensor-specific correction of sensor signals. The ZSSC3286 supports IO-Link connectivity with an integrated IO-Link stack running the IO-Link Smart Sensor Profile for digital measuring and switching sensors. The device is suitable for bridge and half-bridge sensors, as well as external voltage source elements. Digital compensation of the sensor offset, sensitivity, temperature drift, and non-linearity is accomplished via a 32-bit Arm® 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.
