Overview

The ZSSC3136 is a member of the ZSSC313x product family of CMOS integrated circuits for automotive and industrial sensor applications. All family members are well suited for highly-accurate amplification and sensor-specific correction of resistive bridge sensor signals. An internal 16-bit RISC microcontroller running a correction algorithm compensates sensor offset, sensitivity, temperature drift, and non-linearity of the connected sensor element. The required calibration coefficients are stored by the single-pass calibration procedure in an on-chip EEPROM. The ZSSC3136 is optimized for SIL (Safety Integrity Level) rated switch applications. The integrated adjustable digital filter offers the capability to set up fast switching real-time applications as well as stabilized switching applications in the event of disturbed or unstable input signals. In addition to the general features for switch applications, the ZSSC3136 offers the capability to set up safety relevant SIL2-rated switches with extended safety functionalities.

IDT Sensor Signal Conditioner (SSC) Evaluation Kit Overview

A brief introduction and overview of IDT's sensor signal conditioner evaluation kits. Evaluation kits generally consist of three parts: a communication interface board,  a device board, and a sensor simulator board - all connected together. A sophisticated software GUI accompanies the kit, enabling an engineer to learn how to use the part rapidly, do quick prototyping, and practice calibrations.
