ZSSC3154BA1D

Overview

The ZSSC3154BA1D is a Sensor Signal Conditioner (SSC) IC manufactured by Renesas Electronics, belonging to the ZSSC3154 series. It is designed for resistive bridge sensor measurements, providing high-precision amplification, digitization, and sensor-specific correction. The device operates within an input voltage range of 4.5 V to 5.5 V and features an I2C interface. It supports two channels and functions at operating temperatures from -40°C to +125°C with a typical supply current of 10 mA. The component is available in a QFN-32 package suitable for surface mount installation.

Feature Summary

• Optimized for resistive bridge sensor measurements commonly used in air flow sensing applications
• Provides highly accurate amplification, digitization, and sensor-specific calibration of sensor signals
• Supports simultaneous configuration, calibration, and evaluation of multiple units via modular systems

Applications

• Mass Air Flow (MAF) sensing using hot-film flow measurement
• Automotive HVAC sensor signal conditioning
• Industrial resistor-based sensor integration

Procurement Notes

Verify the specific suffix 'BA1D' against official Renesas documentation to confirm it denotes wafer-level or dice form factor rather than standard packaged units. Confirm RoHS compliance status and lead times directly with the manufacturer or authorized distributors, as availability may vary by region and production cycle.

Selection Notes

Select this component when designing systems requiring precise signal conditioning for resistive bridge sensors. Ensure the application environment supports the specified 4.5 V to 5.5 V supply range and that the I2C interface aligns with the host controller's communication protocol. Consider thermal management requirements given the wide operating temperature range.
