REF2030AIDDCT

Overview

The REF2030AIDDCT is a low-drift, low-power dual-output voltage reference from Texas Instruments. It provides precise VREF and VREF/2 outputs in a compact SOT-23-5 Thin package. The device offers an initial accuracy of ±0.05% and a temperature coefficient of 8 ppm/°C. It operates with a maximum input voltage of 5.5 V and draws a supply current of 460 µA. The shunt reference supports a maximum current of 20 mA and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Dual-output architecture providing both VREF and VREF/2 for single-supply system convenience
• Low power consumption with a supply current of 460 µA
• High precision with ±0.05% initial accuracy and 8 ppm/°C temperature drift

Applications

• Single-supply analog front-end systems
• Data acquisition systems requiring stable reference voltages
• Battery-powered instrumentation due to low power profile

Procurement Notes

Verify the specific suffix 'AIDDC' confirms the A-grade accuracy, SOT-23-5 Thin package, and tape-and-reel packaging configuration. Ensure compatibility with your PCB footprint for the TSOT-23-5 form factor. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the manufacturer part number against official Texas Instruments documentation to avoid counterfeit components.

Selection Notes

Select this component when dual output rails are needed without external resistors. The VREF/2 output simplifies biasing circuits in single-supply ADCs. Consider the 8 ppm/°C drift for applications requiring stability over wide temperature ranges. The low 460 µA current makes it suitable for battery-operated devices where power efficiency is critical compared to higher current references.

Part Context

This part belongs to the REF20xx series of low-drift voltage references. It is designed as a drop-in replacement for older discrete reference solutions. The dual-output feature distinguishes it from single-output counterparts like the REF2033. It integrates bandgap technology into a small surface-mount package for space-constrained designs.

Replacement Considerations

Check for REF2030 variants with different accuracy grades or packages. Verify pinout compatibility if substituting with other dual-output references. Ensure thermal performance meets requirements for the specific enclosure environment.
