Overview
The REF3020AIDBZTG4 is a series voltage reference IC 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 ±0.2%. The device operates within an input voltage range of 2.098 V to 5.5 V and draws a maximum supply current of 50 µA. It supports a maximum load current of 25 mA and functions across a temperature range of -40°C to +125°C.
Feature Summary
- Provides a stable fixed reference voltage suitable for precision analog circuits
- Operates with low quiescent current for power-efficient designs
- Capable of sourcing significant load current for driving downstream components
Applications
- Analog-to-digital converter (ADC) reference inputs
- Digital-to-analog converter (DAC) voltage references
- Precision measurement instrumentation signal conditioning
Procurement Notes
Verify component authenticity through authorized channels due to potential counterfeits. Confirm the specific suffix matches required specifications as variations may exist. Check for end-of-life status or obsolescence notices from the manufacturer before finalizing procurement plans to ensure long-term supply availability.
Selection Notes
Select this component when a precise 2.048 V reference is required in a compact SOT-23-3 footprint. Consider the ±0.2% initial accuracy and temperature coefficient for applications demanding high stability. Ensure the operating voltage range aligns with the system power supply constraints.
Part Context
This part belongs to the REF30xx family of series voltage references from Texas Instruments. It shares the same package and general topology as other variants in the series but is distinguished by its specific 2.048 V output voltage setting. It serves as a fundamental building block for precision power management and signal processing systems.
Replacement Considerations
The REF3020AIDBZR is a related variant within the same product line. Verify pin compatibility and electrical specifications before substitution.
