ZSSC3241DI3W

Overview

The ZSSC3241DI3W is a sensor signal conditioning IC from Renesas Electronics, designed for high-precision amplification, digitization, and calibration of resistive sensor signals. It features a 26-bit math core for digital compensation of offset, sensitivity, temperature drift, and non-linearity, with coefficients stored in reprogrammable non-volatile memory. The device supports bridge, half-bridge, and voltage-source sensors. It offers multiple output options including absolute/ratiometric voltage, 4-20mA current loop, and digital interfaces (SPI, I2C, OWI). Operating within a -40°C to +125°C range, it is housed in a 24-QFN (4x4mm) package.

Feature Summary

• Advanced 26-bit math core enables precise digital compensation for sensor offset, sensitivity, temperature drift, and non-linearity using stored calibration coefficients.
• Versatile input compatibility supports various resistive sensor configurations including bridges, half-bridges, and external voltage sources.
• Dual-domain output flexibility allows simultaneous or independent analog outputs (voltage/current loop) and digital communication via SPI, I2C, or OWI.
• Integrated self-diagnostics monitor sensor connection integrity, breakage, and memory status to enhance system safety.

Applications

• Calibrated continuous operation sensors with digital interface and/or analog output
• Pressure, flow, and level sensing in industrial automation
• Smart digital sensors for energy-efficient solutions
• Medical applications such as blood pressure monitors and health trackers
