REF2920AIDBZR

Overview

The REF2920AIDBZR is a precision series voltage reference manufactured by Texas Instruments, housed in an SOT-23-3 surface-mount package. It provides a fixed output voltage of 2.048 V with an initial accuracy of ±2%. The device operates within an input voltage range of 2.098 V to 5.5 V and supports a maximum shunt current of 25 mA. It features a temperature coefficient of 100 ppm/°C and consumes a typical supply current of 42 µA. The component functions reliably across an extended operating temperature range from -40°C to +125°C.

Feature Summary

• Provides a stable fixed output voltage suitable for high-precision analog circuits
• Operates efficiently with low quiescent current consumption
• Designed for reliable performance across wide industrial temperature ranges

Applications

• Analog-to-digital converter (ADC) reference inputs
• Digital-to-analog converter (DAC) voltage references
• Precision measurement instrumentation systems

Procurement Notes

Verify the specific suffix 'DBZR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the ±2% initial accuracy meets the system tolerance requirements, as tighter tolerances are available in other variants within the same family. Ensure the 2.048 V output aligns with the target reference voltage specifications.

Selection Notes

Select this component when a compact SOT-23-3 footprint is required alongside moderate precision levels. The 100 ppm/°C temperature coefficient makes it appropriate for general-purpose applications where extreme thermal stability is not critical. Consider alternative parts if lower noise or higher initial accuracy is necessary for the specific design constraints.

Part Context

This part belongs to the REF2920 series of voltage references from Texas Instruments. It shares the same physical package and basic functionality as other members of the family but offers specific electrical characteristics tailored for cost-sensitive applications requiring standard precision levels.

Replacement Considerations

The REF2920AIDBZT is the identical functional component supplied in cut-tape packaging instead of reel format.
