Overview
The REF2033QDDCRQ1 is an automotive-grade series voltage reference IC manufactured by Texas Instruments. It provides fixed output voltages of 1.65 V and 3.3 V with an initial accuracy of ±0.05%. The device operates within an input voltage range of 2.31 V to 5.5 V and draws a supply current of 460 µA. It features a low temperature coefficient of 8 ppm/°C and supports a maximum shunt current of 20 mA. The component is housed in a SOT-23-THIN (TSOT-23-5) package and is qualified under AEC-Q100 standards for operation between -40°C and +125°C.
Feature Summary
- Automotive qualification compliant with AEC-Q100 standards
- High precision with ±0.05% initial accuracy
- Low power consumption with 460 µA supply current
- Compact surface-mount packaging
Applications
- Automotive sensor signal conditioning
- Data acquisition systems requiring stable references
- Analog-to-digital converter (ADC) reference inputs
- Battery-powered automotive instrumentation
Procurement Notes
Verify the specific output voltage variant (1.65 V or 3.3 V) required for the design, as the base part number may denote the family rather than a single voltage. Confirm that the SOT-23-THIN package dimensions align with the PCB footprint. Ensure the application environment remains within the specified -40°C to +125°C operating temperature range to maintain accuracy specifications.
Selection Notes
Select this component when high accuracy and low drift are critical in space-constrained automotive designs. The low supply current makes it suitable for battery-operated applications where power efficiency is prioritized. Compare the 8 ppm/°C temperature coefficient against system requirements to ensure thermal stability meets the necessary tolerance levels for the intended analog circuitry.
Part Context
This device belongs to the REF2033 family of low-drift, low-power voltage references from Texas Instruments. The 'Q' suffix indicates automotive grade qualification, while 'DDCR' specifies the thin SOT-23-5 package and tape-and-reel shipping method. It serves as a stable reference source for precision analog circuits in harsh automotive environments.
Replacement Considerations
Check for direct cross-reference availability within the same TI family, such as REF2033AIDDCR for non-automotive versions, ensuring package compatibility and electrical parameter alignment before substitution.
