ZSSC3241DL3W

Overview

The ZSSC3241DL3W 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. 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 temperature range is -40°C to +125°C. Package is 24-QFN (4x4mm) in tape and reel format.
