ZSC31010CEB

Overview

The ZSC31010CEB is a CMOS integrated circuit designed as a resistive sensor signal conditioner with analog output capabilities. It facilitates precise calibration of resistive bridge sensors via EEPROM, digitally compensating for offset, gain, temperature drift, and non-linearity. The device accommodates differential sensor signal spans from 3 mV/V to 105 mV/V and supports supply voltages ranging from 2.7 V to 5.5 V, extending to 30 V with an external JFET. Key electrical parameters include a 14-bit resolution, adjustable analog gain options of 6, 12, 24, or 48, and a maximum sample rate of 1 KHz. It operates within a temperature range of -40°C to +85°C and features a ZACwire™ one-wire interface for digital communication.

Feature Summary

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

Applications

• Resistive bridge sensor signal conditioning
• Industrial sensor interfaces requiring high precision
• Applications needing digital calibration of sensor characteristics

Procurement Notes

Verify the specific package type and die configuration associated with the CEB suffix against official Renesas documentation. Confirm that the component meets the required industrial temperature range specifications for your application environment. Ensure compatibility with the host system's ZACwire™ interface requirements before procurement.

Selection Notes

Select this component when digital calibration of resistive bridge sensors is required. It is suitable for applications needing ratiometric or absolute analog voltage outputs. Consider the external JFET requirement if operation above 5.5 V is necessary. Verify that the 14-bit resolution and 1 KHz sample rate meet the system's performance needs.
