ZSSC3240CI1D-ES

Overview

The ZSSC3240CI1D-ES is a sensor signal conditioner IC designed for resistive bridge sensors. It integrates a programmable measurement sequencer, an instrumentation amplifier with gain up to 540 V/V, and a 24-bit ADC. The device features an internal DSP for offset compensation, span adjustment, and first- and second-order temperature compensation using coefficients stored in non-volatile memory. It supports digital interfaces including I2C, SPI, and 1-Wire, and provides analog outputs such as ratiometric voltage or 4-20mA current loops.

Feature Summary

• Integrates 24-bit analog-to-digital conversion with post-processing DSP for linearization and temperature compensation
• Supports flexible output configurations including digital interfaces (I2C, SPI, 1-Wire) and analog signals (voltage or current loop)
• Includes non-volatile memory for storing calibration coefficients and configuration data

Applications

• Calibrated continuously operating sensors with digital interface
• Industrial process and factory automation systems
• Medical applications such as blood pressure monitors and smart health devices

Procurement Notes

Verify the specific suffix 'ES' against official Renesas documentation to confirm if it denotes an engineering sample or special qualification status. Ensure compatibility with the target PCB footprint and voltage levels. Confirm RoHS compliance status through the manufacturer's latest datasheet or environmental declaration before integration into regulated products.

Selection Notes

Select this component when high-resolution signal conditioning for resistive sensors is required without external microcontrollers for basic compensation. Consider the available digital and analog output options to match system interface requirements. Evaluate the package type and operating temperature range (-40°C to +125°C) against environmental constraints.
