Overview
The ZSSC3138BA1D is a CMOS integrated circuit from the ZSSC313x family, designed for automotive and industrial resistive bridge sensor applications. It features an internal 16-bit RISC microcontroller that performs digital compensation for offset, sensitivity, temperature drift, and non-linearity. The device provides an analog gain of 420 with overall gain up to 1680 and supports sample rates up to 7.8 kHz. It offers 15/16-bit ADC resolution and outputs ratiometric analog voltage (12.4-bit) or ZACwire digital signals. Operating within -40°C to +150°C, it includes high-voltage protection up to 33V and max supply current of 5.5mA.
Feature Summary
- Internal 16-bit RISC microcontroller executes correction algorithms for sensor-specific signal conditioning.
- Supports single-pass calibration with coefficients stored in on-chip EEPROM for traceability.
- Provides high amplification combined with offset compensation suitable for ceramic thick-film sensors without laser trimming.
Applications
- Automotive pressure and flow sensors using ceramic thick-film elements
- Industrial resistive bridge sensor signal conditioning
- Applications requiring digital compensation for temperature drift and non-linearity
Procurement Notes
Verify the specific suffix 'BA1D' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing calibration tools and EEPROM programming interfaces. Confirm availability status as distribution channels may vary by region.
Selection Notes
Select this component when high accuracy is required for resistive bridge sensors without post-manufacturing laser trimming. The integrated digital compensation reduces system complexity compared to analog-only solutions. Verify that the 7.8 kHz sample rate meets application bandwidth requirements.
Part Context
The ZSSC3138BA1D belongs to the ZSSC313x product family of sensor signal conditioners. This family targets automotive and industrial markets, offering scalable solutions for resistive bridge sensors. The ZSSC3138 variant specifically emphasizes high gain and resolution for precision applications.
Replacement Considerations
Check Renesas datasheets for direct pin-compatible alternatives within the ZSSC313x family. Verify if ZSSC3131 or other variants meet the specific gain and resolution needs. Ensure any substitute supports the same ZACwire interface and EEPROM calibration method.
