Overview
The REF4132B25DBVR is a precision series voltage reference manufactured by Texas Instruments, designed for automotive and industrial applications. It delivers a fixed output voltage of 2.5 V with an initial accuracy of ±0.05%. The device features a low temperature coefficient of 12 ppm/°C and operates within an extended junction temperature range from -40°C to +125°C. It supports a maximum input voltage of 5.5 V and draws a typical supply current of 100 µA. The component is housed in a compact SOT-23-5 surface-mount package.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Low-noise performance suitable for sensitive analog circuits
- Compact SOT-23-5 footprint for space-constrained designs
Applications
- Automotive sensor signal conditioning
- Data acquisition systems
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'B' against the official Texas Instruments datasheet to confirm the exact output tolerance and temperature coefficient specifications. Ensure the Q1 designation is present if automotive qualification is required for your application. Cross-reference the package marking code to distinguish between standard and qualified variants during incoming inspection.
Selection Notes
Select this component when a stable 2.5 V reference is needed in small form factors. Compare the 12 ppm/°C drift against higher precision alternatives like the REF34xx series if tighter thermal stability is required. Consider the 100 µA quiescent current for battery-powered designs versus the lower consumption options available in other families.
Part Context
This part belongs to the REF4132 family of low-drift, low-power series voltage references. It shares functional similarities with the LM4132 but offers enhanced automotive qualification. The device serves as a drop-in replacement for older generation references requiring similar pinouts and electrical characteristics in precision measurement applications.
Replacement Considerations
The REF4132B25DBVRQ1 is a verified automotive-qualified substitute offering identical electrical performance with added reliability testing. Verify that the 'Q1' suffix meets specific OEM quality requirements before substitution.
