REF4132A33DBVR

Overview

The REF4132A33DBVR is a precision series voltage reference manufactured by Texas Instruments, housed in an SOT-23-5 package. It provides a fixed output voltage of 3.3 V 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 3.05 V to 5.5 V. It draws a supply current of 100 µA and supports a maximum output current of 10 mA. The component is rated for operation between -40°C and +125°C.

Feature Summary

• Delivers high-precision voltage regulation with ±0.05% initial accuracy
• Maintains stability across wide thermal ranges via a 12 ppm/°C temperature coefficient
• Operates efficiently with a 100 µA supply current draw

Applications

• Precision analog-to-digital converter (ADC) reference sources
• Data acquisition systems requiring stable voltage baselines
• Medical instrumentation circuits
• Industrial process control monitoring

Procurement Notes

Verify the specific suffix 'A33' confirms the 3.3 V fixed output variant. Confirm the 'Q1' designation if automotive qualification under AEC-Q100 standards is required for your application. Ensure the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is needed for high-accuracy applications. The 12 ppm/°C drift rate makes it suitable for environments with significant temperature fluctuations. Compare against standard references if lower cost is prioritized over the ±0.05% tolerance provided by this specific part.

Part Context

This part belongs to the REF4132 family of low-noise, micropower series voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The DBVR suffix indicates the specific SOT-23-5 packaging style used for space-constrained designs.

Replacement Considerations

The REF4132A33DBVRQ1 is a qualified automotive-grade alternative within the same family. Other REF4132 variants with different output voltages or accuracy grades may serve as functional substitutes if electrical parameters align with system requirements.
