REF35170QDBVR

Overview

The REF35170QDBVR is a shunt precision voltage reference from the Texas Instruments REF35 series, housed in an SOT-23-6 package. It features an initial accuracy of 0.05% and a temperature coefficient of 12 ppm/°C. The device operates within a supply voltage range up to 6 V and supports a shutdown function. It is qualified for automotive applications and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Provides stable shunt precision voltage referencing with high initial accuracy
• Includes a dedicated shutdown pin for power management control
• Qualified for automotive environments ensuring reliability under harsh conditions

Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring precise voltage benchmarks
• Battery management system monitoring interfaces

Procurement Notes

Verify the specific suffix QDBVR matches the required automotive qualification and package type. Confirm RoHS compliance status through official documentation before integration. Ensure the ordering quantity aligns with manufacturer packaging constraints such as cut tape or reel sizes. Cross-reference the datasheet revision date to guarantee parameter consistency during procurement.

Selection Notes

Select this component when a low-drift, automotive-grade shunt reference is required in a compact SOT-23-6 footprint. It is suitable for designs needing 0.05% initial accuracy and operation up to 125°C. Consider the 12 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 6 V maximum input voltage against the system supply rails.

Part Context

This part belongs to the REF35 family of precision voltage references designed for high-reliability applications. The REF35 series offers various output voltages and packages, with the QDBVR variant specifically tailored for automotive use. It complements other Texas Instruments power management solutions by providing accurate reference signals for analog-to-digital conversion and regulation loops.

Replacement Considerations

Check for direct cross-references within the REF35 family for different voltage outputs. Verify if non-automotive grades meet the environmental specifications if cost reduction is prioritized. Ensure pinout compatibility when substituting with similar shunt references from other manufacturers.
