ZSC31050FID

Overview

The ZSC31050FID is an advanced differential sensor signal conditioner manufactured by Renesas Electronics Corporation. It is designed for amplification and sensor-specific correction of bridge sensor signals using a 16-bit RISC microcontroller. The device accommodates resistive bridge sensors, such as piezoresistive pressure sensors, with input signals ranging from 1mV/V to 275mV/V. It provides digital compensation for offset, sensitivity, temperature drift, and non-linearity. The component supports multiple output options including voltage (0V to 5V), current (4mA to 20mA), PWM, I²C, SPI, and ZACwire™ interfaces. It operates on a supply voltage of +2.7V to +5.5V and features adjustable ADC resolution up to 15-bit.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity via internal microcontroller
• Accommodates nearly all bridge sensors through programmable PGA and ADC capabilities
• Supports multiple output formats including analog voltage, current loop, PWM, and various digital protocols
• Includes diagnostic functions for sensor connection checks and aging detection

Applications

• Industrial pressure sensing systems
• Medical instrumentation requiring precise signal conditioning
• Consumer applications utilizing force or torque sensors

Procurement Notes

Verify the specific suffix 'FID' against official Renesas documentation to confirm package type and availability status. Ensure compatibility with required operating temperatures and interface configurations before procurement. Cross-reference with authorized distributors for current stock levels and lead times.

Selection Notes

Select this component when digital calibration and high-accuracy signal conditioning are required for bridge sensors. Consider the available output options and interface requirements. Verify that the operating temperature range meets application needs. Compare with similar models like ZSC31050FIG1-R for package differences.

Part Context

The ZSC31050 series includes variants such as ZSC31050FEC (Die) and ZSC31050FIG1-R (SSOP-16). The ZSC31050FID is part of this family of advanced differential sensor signal conditioners. It shares core functionalities with other series members but may differ in packaging or specific electrical characteristics based on the suffix.

Replacement Considerations
