ZSC31014EIG1-R

Overview

The ZSC31014EIG1-R is a RBiciLite digital output sensor signal conditioner manufactured by Renesas Electronics. It provides high-accuracy amplification and analog-to-digital conversion of differential input signals from resistive bridge sensors. The device performs offset, span, and first- and second-order temperature compensation using an internal digital signal processor. Calibration coefficients are stored in nonvolatile EEPROM. It features configurable I²C or SPI digital outputs for compensated bridge values and optional temperature data. The component operates within a -40°C to 85°C temperature range and is housed in an 8-pin SOP package.

Feature Summary

• Integrates a digital signal processor for real-time correction of signal offset, sensitivity, temperature drift, and non-linearity.
• Stores calibration coefficients in highly reliable nonvolatile EEPROM to eliminate external trimming overhead.
• Supports both I²C and SPI interfaces for flexible system integration and programming via PC-controlled software.
• Includes integrated diagnostic functions and a low-power standby mode for enhanced operational efficiency.

Applications
