ZSC31050FIG1-T

Overview

The ZSC31050FIG1-T is a CMOS integrated circuit designed for the amplification and sensor-specific correction of bridge sensor signals. It features digital compensation for offset, sensitivity, temperature drift, and non-linearity via an internal 16-bit RISC microcontroller. The device accommodates resistive bridge sensors with signal spans from 1mV/V to 275mV/V. It supports multiple output options including voltage (0V to 5V), current (4mA to 20mA), PWM, I2C, SPI, and ZACwire™ interfaces. Operating on a supply voltage of +2.7V to +5.5V, it functions within a temperature range of -40 °C to +150 °C and is housed in a 16-SSOP package.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity using a 16-bit RISC microcontroller.
• Accommodates nearly all bridge sensors via programmable gain amplifier and adjustable ADC resolution up to 15-bit.
• Provides versatile output options including analog voltage, current loop, PWM, and various digital serial interfaces.
• Includes diagnostic capabilities such as sensor connection checks and aging detection.

Applications

• Industrial pressure sensors
• Medical force and torque measurement systems
• Automotive acceleration and position sensing

Procurement Notes

Verify the specific suffix 'FIG1' against official Renesas documentation to confirm interface configuration and package variant. Ensure compatibility with system power supplies within the 2.7V to 5.5V range. Confirm that the SSOP-16 footprint matches the PCB layout requirements. Check for AEC-Q100 qualification if automotive grade reliability is required for the specific revision.

Selection Notes

Select this component when high-precision digital calibration of resistive bridge sensors is required. It is suitable for applications needing flexible output formats like 4-20mA or digital communication. Consider the operating temperature range and supply voltage constraints. Evaluate if the integrated diagnostics meet safety requirements compared to other series members like the ZSC31150.

Part Context

This part belongs to the ZSC31050 family of advanced differential sensor signal conditioners. It shares core functionality with variants like the ZSC31050FEG1-T but differs in interface support and packaging. The family is designed for industrial, medical, and consumer applications requiring precise signal conditioning for piezoresistive and steel-membrane-based sensors.
