REF4132A30DBVR

Overview

The REF4132A30DBVR is a precision series voltage reference manufactured by Texas Instruments, designed for automotive applications. It provides a fixed output voltage of 3V with an initial accuracy of ±0.05%. The device features a low temperature coefficient of 12 ppm/°C and operates within an input voltage range of 3.05V to 5.5V. It supports a maximum output current of 10 mA and consumes 100 µA of supply current. The component is housed in a SOT-23-5 package and is qualified under AEC-Q100 standards, ensuring reliability across a wide operating temperature range from -40°C to +125°C.

Feature Summary

• Automotive-grade qualification compliant with AEC-Q100 standards for enhanced reliability
• Low noise performance with specified RMS and peak-to-peak values
• High precision stability characterized by low temperature coefficient and tight initial accuracy

Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring stable reference voltages
• Precision analog-to-digital converter (ADC) references

Procurement Notes

Verify the specific suffix 'Q1' or absence thereof against official datasheets to confirm automotive grade status. Ensure the package type matches the design requirements. Confirm RoHS compliance and lead times through authorized distributors. Cross-reference part numbers carefully as minor suffix variations may indicate different packaging or temperature grades.

Selection Notes

Select this component when automotive certification and high precision are required in a compact surface-mount package. Compare noise specifications and quiescent current against other series references if power efficiency is critical. Verify that the 3V output aligns with system voltage requirements and that the SOT-23-5 footprint fits the PCB layout constraints.

Part Context

This part belongs to the REF4132 family of low-noise, low-power precision voltage references. The family includes various output voltages and packages, catering to both industrial and automotive markets. The REF4132 series is distinguished by its combination of low drift, low noise, and small form factor, making it suitable for space-constrained high-performance applications.

Replacement Considerations

Check for LM4132 variants for similar functionality but potentially different automotive qualification. Verify pinout compatibility before substituting with other SOT-23-5 voltage references. Ensure replacement parts meet the same AEC-Q100 requirements if used in automotive designs.
