ZSSC3240CC5C

Overview

The ZSSC3240CC5C is a sensor signal conditioning integrated circuit designed for high-precision measurement applications. It features a 24-bit analog-to-digital converter and an internal digital signal processing core that performs 26-bit sensor-specific correction, including auto-zero, span adjustment, and first- and second-order temperature compensation using coefficients stored in non-volatile memory. The device supports resistive bridge sensors, Pt100 platinum resistance thermometers, and diode-type thermometers via an on-chip current source. Operating voltage ranges from 2.7 V to 5.5 V, with a functional temperature range of -40°C to +125°C.

Feature Summary

• Integrates a programmable measurement sequencer for multiplexing between bridge, temperature, and diagnostic measurements.
• Provides amplification with gain factors up to 540V/V to optimize the ADC input range.
• Includes an on-chip temperature sensor and supports external temperature sensing capabilities.
• Features a math core for digital compensation of offset, sensitivity, temperature drift, and non-linearity.

Applications

• Industrial pressure sensors utilizing resistive bridge elements.
• High-accuracy temperature measurement systems using Pt100 or diode-type thermometers.
• Sensor platforms requiring linearized and temperature-compensated output values.

Procurement Notes

Verify the specific suffix CC5C against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with the required operating voltage and temperature range for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when high-resolution digitization and onboard calibration are required for resistive sensors. Consider the ZSSC3241 if additional analog output options like DAC clipping or separate AOUT post-scaling are needed, as it offers enhanced flexibility while maintaining backward compatibility.

Part Context

The ZSSC3240 belongs to Renesas' Sensor Signal Conditioning (SSC) portfolio, aimed at simplifying sensor platform development. It replaces traditional discrete amplifier and ADC solutions by integrating signal processing, digitization, and correction into a single chip, reducing system complexity and improving accuracy.

Replacement Considerations

The ZSSC3241 is a compatible alternative offering enhanced AFE configuration options and programmable DAC output clipping. It maintains the same die size and QFN24-pin-out layout, ensuring mechanical interchangeability while providing additional digital compensation features.
