Overview
The REF3430TIDBVR is a precision series voltage reference from Texas Instruments, housed in an SOT-23-6 surface-mount package. It provides a fixed output of 3 V with an initial accuracy of 0.05%. The device features a low temperature coefficient of 2.5 PPM/C and operates within an input voltage range of 3.05 V to 12 V. It draws a typical supply current of 72 uA and supports a shutdown function. The component is rated for operation between -40 C and +125 C.
Feature Summary
- Provides high-precision voltage regulation with 0.05% initial accuracy
- Features ultra-low temperature drift of 2.5 PPM/C for thermal stability
- Includes a dedicated shutdown pin for power management
- Designed for small-footprint applications with low quiescent current
Applications
- Portable instrumentation requiring precise voltage references
- Battery-powered measurement systems
- Data acquisition systems
- Industrial process control loops
Procurement Notes
Verify the suffix IDBVR confirms the specific temperature grade and packaging configuration required for your design. Ensure compatibility with the 3.05 V to 12 V input range. Confirm that the SOT-23-6 footprint matches your PCB layout constraints. Check for moisture sensitivity level requirements during assembly processing.
Selection Notes
Select this component when superior thermal stability is critical compared to standard 6 PPM/C alternatives like the REF3430IDBVR. The lower drift rate makes it suitable for high-accuracy applications where temperature variations are significant. Consider the slightly higher cost relative to standard grades against the benefit of reduced calibration needs.
Part Context
This part belongs to the REF34xx family of low-power, precision voltage references. It shares the same SOT-23-6 form factor as other members but offers distinct performance characteristics regarding temperature coefficient. It serves as a high-stability alternative within the portfolio for demanding analog signal conditioning tasks.
Replacement Considerations
The REF3430IDBVR is a related variant with a 6 PPM/C temperature coefficient. Verify if the stricter 2.5 PPM/C specification is necessary for your application before substituting.
