ZSC31010CIG1-R

Overview

The ZSC31010CIG1-R 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 sample rates up to 1 kHz, and current consumption between 0.25 mA and 1 mA depending on the sample rate. It features a wide operational temperature range from -50°C to +150°C and provides buffered, chopper-stabilized output.

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
• Pressure sensor interfaces
• Force and torque measurement systems

Procurement Notes

Verify the specific suffix CIG1-R against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with host systems requiring ZACwire™ interface support. Confirm that external components, such as JFETs for extended voltage ranges, are sourced according to the datasheet requirements. Cross-reference the part number with authorized distributors to ensure authenticity and traceability.

Selection Notes

Select this component when digital calibration of resistive bridge sensors is required to correct for temperature drift and non-linearity. It is suitable for applications needing ratiometric or absolute analog outputs alongside digital data access. Consider the supply voltage constraints and the necessity for high-voltage protection if operating beyond 5.5 V without external circuitry. Evaluate the need for ZACwire™ integration versus other serial interfaces available in the family.
