REF2030QDDCRQ1

Overview

The REF2030QDDCRQ1 is an automotive-grade, low-drift, dual-output voltage reference IC from Texas Instruments. It provides a fixed 3V output with an initial accuracy of ±0.05% and a temperature coefficient of 8 PPM/°C. The device operates within an input voltage range of 2.28V to 5.5V and draws a supply current of 460µA. It supports an ambient operating temperature range from -40°C to +125°C and is housed in a SOT-23-THIN package.

Feature Summary

• Dual-output architecture providing both VREF and VBIAS for biasing bipolar signals
• Automotive qualification compliant with AEC-Q100 standards
• Low-power consumption suitable for battery-operated applications

Applications

• Analog-to-digital converter (ADC) reference voltage generation
• Biasing input bipolar signals in measurement systems
• Automotive sensor signal conditioning circuits

Procurement Notes

Verify the specific suffix 'QDDCRQ1' matches your design requirements, as it denotes the automotive grade, package type, and tape-and-reel packaging configuration. Confirm that the 3V output voltage aligns with your system's reference needs. Ensure the SOT-23-THIN footprint is compatible with your PCB layout. Check for any specific handling or storage instructions related to the automotive qualification status.

Selection Notes

Select this component when a stable, low-drift reference is required for automotive ADC applications. The dual-output feature simplifies biasing circuits by providing a dedicated VBIAS. Consider the 8 PPM/°C temperature coefficient for precision requirements across the full industrial temperature range. The low supply current makes it suitable for power-sensitive designs compared to higher-current alternatives.

Part Context

This part belongs to the REF20xx-Q1 family of low-drift, low-power voltage references designed for automotive environments. The family offers various fixed output voltages and accuracies. The REF2030 variant specifically provides a 3V output. These devices are engineered to meet stringent automotive reliability standards while maintaining high precision in noisy environments.

Replacement Considerations

Check for other members of the REF20xx-Q1 family with different output voltages if 3V is not required. Verify compatibility with alternative automotive-grade voltage references from other manufacturers if supply constraints exist. Ensure pinout and thermal characteristics match if substituting with non-TI components.
