ZSC31050FAG1-R

Overview

The ZSC31050FAG1-R 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 input signals ranging 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™. Operating on a supply voltage of +2.7V to +5.5V, it is housed in a 16-SSOP package and qualified to AEC-Q100 standards.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• Multiple output options including voltage, current, PWM, and digital interfaces
• Accommodates nearly all bridge sensors via programmable PGA and ADC
• AEC-Q100 qualification for automotive reliability

Applications

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

Procurement Notes

Verify the specific suffix 'FA' against official Renesas documentation to confirm pinout and functional variations compared to standard variants. Confirm availability status as some ZSC31050 series components may be discontinued or subject to PCN changes. Ensure the selected package matches the target PCB footprint requirements.

Selection Notes

Select this component when digital calibration of bridge sensors is required to reduce external analog complexity. Consider the available interface options (I2C, SPI, ZACwire) for system integration needs. Evaluate the operating temperature range and supply voltage constraints against the application environment before finalizing the design.

Part Context

The ZSC31050FAG1-R belongs to the ZSC31050 family of advanced differential sensor signal conditioners. This series is designed to simplify the interface between resistive bridge sensors and microcontrollers by handling signal conditioning and linearization internally. Other variants in the family include ZSC31050DEG1-R and ZSC31050FIG1-R.

Replacement Considerations

Check for direct substitutes within the ZSC31050 family such as ZSC31050FIG1-R or ZSC31050FEG1-R. Verify compatibility with existing calibration coefficients and software tools if replacing an older variant.
