ZSSC3036CI4W

Overview

The ZSSC3036CI4W is a low-power, high-resolution 16-bit sensor signal conditioner integrated circuit designed for accurate 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 ADC. The device includes a fully programmable gain amplifier accepting sensors from 14 to 72 linear factor, internal auto-compensated temperature sensing, and digital compensation for individual sensor offset, gain, and temperature drift. It supports I2C (≤ 3.4MHz) or SPI (≤ 20MHz) digital output interfaces.

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
• Fast sensing capability providing 16-bit conditioned sensor signal measurement rate at more than 200s-1

Applications

• High-resolution altimeter module applications
• Resistive bridge sensor correction
• Corrected temperature output measurement

Procurement Notes

Verify the specific suffix CI4W against official Renesas documentation, as public records primarily list variants such as CC1B, CC1C, CC6B, and CI1B. Confirm current lifecycle status, as many ZSSC3036 variants are marked obsolete or last-time-buy. Ensure compatibility with required operating temperature ranges (-40 to 85°C or -40 to 110°C) and interface configurations before procurement.

Selection Notes

Select this component when high-accuracy amplification and analog-to-digital conversion of differential signals are required. It is suitable for applications needing offset, span, and temperature compensation via an internal 18-bit DSP. Consider the available digital output interfaces, I2C or SPI, and ensure the programmable gain amplifier range meets the specific sensor requirements.

Part Context

The ZSSC3036 series belongs to Renesas' sensor signal conditioner family, optimized for high-resolution applications like altimeters. It integrates analog front-end processing with digital compensation capabilities, allowing for precise correction of resistive bridge sensors. The device simplifies system design by handling complex calibration algorithms internally.

Replacement Considerations

Public data indicates variants like ZSSC3036CC1B, CC1C, CC6B, and CI1B are obsolete or last-time-buy. Verify if other ZSSC303x family members or newer Renesas SSC models serve as direct functional substitutes, ensuring pinout and feature compatibility.
