ZSSC3026CC1B

Overview

The ZSSC3026CC1B is a sensor signal conditioner integrated circuit designed for high-accuracy amplification and analog-to-digital conversion of differential input signals. It features a flexible, programmable analog front-end with a scalable, charge-balancing two-segment analog-to-digital converter capable of up to 16-bit resolution. The device includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor. Internal digital compensation corrects individual sensor offset, gain, and temperature drift using an 18-bit internal digital signal processor. Calibration coefficients are stored in non-volatile multiple-time programmable memory.

Feature Summary

• Flexible, programmable analog front-end design with up to 16-bit scalable, charge-balancing two-segment analog-to-digital converter
• Fully programmable gain amplifier accepting sensors from 14 to 72 linear factor
• Internal auto-compensated temperature sensor with digital compensation of individual sensor offset, gain, and temperature drift
• Intelligent power management unit with layout customized for die-die bonding with sensor for high-density chip-on-board assembly

Applications

• High-resolution altimeter module applications
• Resistive bridge sensor correction
• High-accuracy pressure sensing systems

Procurement Notes

Verify the specific suffix 'CC1B' against official Renesas documentation, as public records primarily reference the base ZSSC3026 series or variants like CI1B. Confirm current production status, as the broader ZSSC3026 family has been marked as obsolete in some distributor listings. Ensure compatibility with existing calibration tools and serial interface requirements (I2C or SPI) before procurement.

Selection Notes

Select this component when designing systems requiring precise digital compensation for resistive bridge sensors. The ZSSC3026CC1B supports both I2C and SPI interfaces for calibration coefficient programming. Consider the package type suitable for die-die bonding if integrating directly with sensor dies. Verify that the required accuracy meets the typical specification of less than ±0.10% FSO over the operating temperature range.

Part Context

The ZSSC3026 belongs to Renesas' Sensor Signal Conditioner family, developed specifically for correcting resistive bridge sensors. It integrates an 18-bit DSP for running correction algorithms and stores calibration data in on-chip MTP memory. The series is optimized for applications demanding high resolution and low power consumption, such as altimeters and precision pressure sensors.

Replacement Considerations

Publicly confirmed substitute part numbers for the specific ZSSC3026CC1B variant are not available in standard distributor databases. Engineers should consult Renesas technical support for direct replacements or evaluate other members of the ZSSC30xx family, ensuring pinout and functional compatibility.
