Overview
Description
The ZSSC3138 is a member of the ZSSC313x product family of CMOS integrated circuits designed 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 ZSSC3138 offers a maximum analog gain of 420 and two offset compensation features. These fit the requirements of ceramic thick-film-based sensor elements as well as strain gauges perfectly. The high amplification in combination with the offset compensation offers the capability to set up ceramic-thick-film-based sensor applications without laser trimming, which leads to better long-term stability.

IDT Sensor Signal Conditioner (SSC) Evaluation Kit Overview
A brief introduction and overview of IDT's (acquire by Renesas) 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.
Presented by David Grice, applications engineer at IDT. For more information about IDT's sensor signal conditioner products, visit the Sensor Signal Conditioner page.
