ZSSC3026CI4WH

Overview

The ZSSC3026CI4WH is a sensor signal conditioner integrated circuit manufactured by Renesas Electronics Corporation. It provides high-accuracy amplification and analog-to-digital conversion for differential input signals, specifically designed for high-resolution altimeter module applications. The device features a flexible, programmable analog front-end with a scalable, charge-balancing two-segment analog-to-digital converter capable of 16-bit resolution. It includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor. Digital compensation for offset, span, gain, and temperature drift is handled by an internal 18-bit digital signal processor using calibration coefficients stored in non-volatile 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
• Digital compensation of 1st and 2nd order sensor gain and temperature drift
• Intelligent power management unit optimized for die-die bonding with sensor for high-density chip-on-board assembly

Applications

• High-resolution altimeter module applications
• Correction of resistive bridge sensors
• IoT sensor signal conditioning requiring high accuracy

Procurement Notes

Verify the exact suffix CI4WH against official Renesas documentation to confirm package type and tape/reel specifications. Confirm current lifecycle status as distribution data indicates potential end-of-life or limited availability for this component family. Ensure compatibility with existing calibration tools and software drivers before procurement.

Selection Notes

Select the ZSSC3026 series when designing systems requiring precise correction of resistive bridge sensors with minimal external components. The internal DSP and MTP memory simplify calibration processes compared to discrete solutions. Verify that the required gain range (14 to 72) and accuracy specifications (less than ±0.10% FSO) align with the target sensor characteristics.

Part Context

The ZSSC3026 belongs to Renesas' Sensor Signal Conditioner (SSC) portfolio, aimed at simplifying IoT sensor integration. It complements Renesas MCU offerings by handling analog front-end tasks digitally. This specific part supports rapid prototyping through standardized interfaces like I2C and SPI, reducing driver code requirements for system designers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Renesas technical support for direct replacements or pin-compatible alternatives within the SSC family if this specific suffix is discontinued.
