ZSC31050FIB

Overview

The ZSC31050FIB is a CMOS integrated circuit functioning as an advanced differential sensor signal conditioner, manufactured by Renesas Electronics. It is designed for the amplification and sensor-specific correction of bridge sensor signals, accommodating virtually any resistive bridge sensor such as piezoresistive and steel-membrane-based pressure sensors. The device integrates a 16-bit RISC microcontroller to perform digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity via a correction algorithm. It supports bidirectional digital interfaces including I2C, SPI, and ZACwire for calibration coefficient programming into on-chip EEPROM. The component operates within a supply voltage range of +2.7V to +5.5V and is available in SSOP-16 or die form factors.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity using internal 16-bit RISC microcontroller
• Accommodates nearly all bridge sensors via programmable gain amplifier (PGA) and programmable ADC
• Multiple output options including voltage, current, PWM, I2C, SPI, ZACwire, and alarm capabilities
• Adjustable ADC resolution up to 15-bit with sampling rates up to 3.9kHz

Applications

• Industrial pressure sensors
• Medical force and torque sensors
• Consumer acceleration and position sensors

Procurement Notes

Verify the specific suffix 'FIB' against official Renesas documentation to confirm package type and tape/reel specifications. Ensure compatibility with required operating temperatures and interface protocols before integration. Confirm availability through authorized distributors as lead times may vary based on production schedules.

Selection Notes

Select this component when high-precision conditioning of resistive bridge sensors is required. Consider the integrated digital compensation features to reduce external calibration components. Verify that the available output formats meet system requirements. Check AEC-Q100 qualification status if automotive applications are intended.
