ZSSC3138BA2T

Overview

The ZSSC3138BA2T is a CMOS integrated circuit from the ZSSC313x family, designed for automotive and industrial resistive bridge sensor applications. It provides high-accuracy amplification and sensor-specific correction of signals. Key electrical parameters include an analog gain of 420, overall gain up to 1680, and sample rates up to 7.8 kHz. The device features 15/16-bit ADC resolution and supports ratiometric analog voltage output (12.4-bit) or Zacwire digital interface. Supply current is max 5.5 mA with reverse polarity protection.

Feature Summary

• Adjustable to nearly all resistive bridge sensor types
• Internal temperature compensation and digital correction of offset, sensitivity, drift, and non-linearity
• High voltage protection up to 33V
• Traceability via user-defined EEPROM entries

Applications

• Automotive ceramic thick-film-based sensor applications
• Industrial strain gauge signal conditioning
• Sensor systems requiring laser-trimming-free setup

Procurement Notes

Verify the specific suffix BA2T against official Renesas documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance and automotive qualification status directly with the manufacturer or authorized distributors before procurement.

Selection Notes

Select this component when designing systems using resistive bridge sensors that require high accuracy without post-manufacturing laser trimming. Ensure the application environment falls within the -40°C to +150°C operating range and requires either analog voltage or Zacwire digital output interfaces.

Part Context

This part belongs to the ZSSC313x product family of CMOS ICs. Members of this family are optimized for highly accurate amplification and correction of resistive bridge sensor signals using an internal 16-bit RISC microcontroller and on-chip EEPROM for calibration coefficients.

Replacement Considerations

Other members of the ZSSC313x family may serve as alternatives if pin compatibility and specific gain requirements align. Verify functional equivalence through official cross-reference data.
