ZSSC3026CI6B

Overview

The ZSSC3026CI6B is a sensor signal conditioner integrated circuit designed for high-accuracy amplification and analog-to-digital conversion of differential input signals. It features a scalable, charge-balancing two-segment analog-to-digital converter with up to 16-bit resolution. The device includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor. It performs digital compensation for individual sensor offset, gain, and first and second-order temperature drift. Calibration coefficients are stored in non-volatile multiple-time programmable memory. Digital outputs support I2C at frequencies up to 3.4MHz or SPI at frequencies up to 20MHz.

Feature Summary

• Flexible, programmable analog front-end design with scalable charge-balancing ADC
• Internal auto-compensated temperature sensor for digital correction of drift
• Intelligent power management unit optimized for die-die bonding assembly

Applications

• High-resolution altimeter module applications
• Resistive bridge sensor signal conditioning
• High-density chip-on-board assembly with sensor elements

Procurement Notes

Verify the specific suffix CI6B against official Renesas documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as distributors may list this part as obsolete or end-of-life. Ensure calibration tools and software compatibility with the MTP programming interface are available before procurement.

Selection Notes

Select this component when designing systems requiring precise digital compensation for resistive bridge sensors. Verify that the required gain range falls between 14 and 72. Ensure the host system supports either I2C or SPI interfaces for downloading calibration coefficients into the internal non-volatile memory during the manufacturing process.

Part Context

This part belongs to the ZSSC3026 family of sensor signal conditioners developed by Renesas Electronics. It is specifically engineered for correcting resistive bridge sensors in demanding environments. The device integrates an 18-bit internal digital signal processor to execute correction algorithms, distinguishing it from standard amplifiers by providing calibrated digital outputs directly.

Replacement Considerations

Consult official Renesas replacement guides for obsolescence notices. No direct public substitute part numbers are confirmed in the provided data. Verify pinout and functional compatibility if considering alternative sensor signal conditioners from other manufacturers.
