ZSC31010CED

Overview

The ZSC31010CED is a CMOS integrated circuit designed as a resistive sensor signal conditioner. It enables precise calibration of resistive bridge sensors via EEPROM, digitally compensating for offset, gain, and temperature drift. The device accommodates differential sensor signals ranging from 3 mV/V to 105 mV/V. It features the ZACwire one-wire interface for communication and includes internal temperature compensation using bandgap PTAT circuits. Supply voltage ranges from 2.7 V to 5.5 V, extending to 30 V with an external JFET. Current consumption varies between 0.25 mA and 1 mA based on sample rate. The operational range spans -50°C to +150°C with a fast response time of 1 ms.

Feature Summary

• Digital compensation of sensor offset, sensitivity, temperature drift, and non-linearity
• ZACwire one-wire interface for serial communication
• Internal temperature compensation and detection via bandgap PTAT
• Buffered and chopper-stabilized output DAC

Applications

• Resistive bridge sensor signal conditioning
• Pressure sensor applications
• Force and torque measurement systems

Procurement Notes

Verify the specific suffix 'CED' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and reflow profiles. Confirm that the die or wafer sawn format matches assembly requirements. Validate supply chain authenticity through authorized channels.

Selection Notes

Select this component when digital calibration of resistive bridges is required without complex external processing. Consider the ZACwire interface if single-wire communication is preferred. Evaluate power constraints against the 0.25 mA to 1 mA consumption range. Verify that the 30 V protection limit with external JFET meets system voltage requirements.

Part Context

The ZSC31010 belongs to the ZSC310xx family of sensor signal conditioners by Renesas. This series focuses on simplifying sensor integration by handling amplification and correction internally. Other members like the ZSC31050 offer additional interfaces such as I2C and SPI, while the ZSSC3131 targets cost-optimized switch applications.
