Overview
Description
The ZSC31050 is a CMOS integrated circuit for amplification and sensor-specific correction of bridge sensor signals. The device provides digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity by a 16-bit RISC microcontroller running a correction algorithm. The ZSC31050 accommodates virtually any resistive bridge sensor (e.g., piezoresistive and steel-membrane-based pressure sensors). In addition, the device can interface to a separate temperature sensor. The bidirectional digital interfaces (I2C, SPI, ZACwire™) can be used for a simple PC-controlled calibration procedure, encompassing writing and programming a set of calibration coefficients into an on-chip EEPROM. The ZSC31050 has been designed for industrial, medical, and consumer applications and is specifically suited for most pressure sensors. It can also be used with force, torque, acceleration, angle, position, and revolution sensors.

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.
