ZSC31050FEG1-R

Overview

The ZSC31050FEG1-R is an advanced differential sensor signal conditioner manufactured by Renesas Electronics. It integrates a 16-bit RISC microcontroller for digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity. The device accommodates resistive bridge sensors with signals ranging from 1mV/V to 275mV/V via a programmable gain amplifier and ADC. It supports multiple output options including voltage (0V to 5V), current (4mA to 20mA), PWM, I2C, SPI, and ZACwire™. Operating temperatures reach up to +150°C, and it is AEC-Q100 qualified for Grade 0. Supply voltage ranges from 2.7V to 5.5V, or 5V to 40V with an external JFET.
