ZSSC3240CL1B

Overview

The ZSSC3240CL1B is a sensor signal conditioner IC from Renesas Electronics Corporation, designed for high-precision amplification and digitization of resistive bridge sensors. It features a programmable measurement sequencer that multiplexes between bridge, temperature, or diagnostic measurements. The device provides offset compensation and amplification with a gain factor up to 540V/V, followed by digitization with up to 24-bit resolution. Post-processing via an internal DSP ensures linearized and temperature-compensated values. Output options include digital interfaces (SPI, I2C, OWI), absolute or ratiometric analog voltage, and industrial current loops.

Feature Summary

• Supports flexible input/output configurations including SPI, I2C, OWI, analog voltage, and current loop outputs.
• Integrates a programmable measurement sequencer for multiplexing bridge, temperature, and diagnostic readings.
• Features a 24-bit main math kernel for sensor signal conditioning with internal DSP post-processing.

Applications

• Calibrated continuous operation sensors with digital or analog outputs
• Smart digital sensors for energy-efficient solutions
• Pressure, flow, and level detection systems

Procurement Notes

Verify the specific suffix CL1B against official Renesas documentation to confirm package type and temperature range.
