Overview
The TL4050B25QDCKR is an automotive-grade precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 2.5 V with an initial accuracy of 0.2% and a temperature coefficient of 50 PPM/C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum shunt current of 15 mA. It is housed in a compact SC-70-5 surface-mount package and complies with the AEC-Q100 qualification standard for automotive applications.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards
- High precision with 0.2% initial accuracy tolerance
- Micropower operation suitable for space-constrained designs
Applications
- Automotive sensor signal conditioning
- Data acquisition systems requiring stable references
- Battery management system monitoring circuits
Procurement Notes
Verify that the specific part number suffix matches the required package type and quality grade. Confirm AEC-Q100 compliance is necessary for the intended automotive application. Check for any recent product change notifications regarding packaging or manufacturing site updates before finalizing procurement orders.
Selection Notes
Select this component when a fixed 2.5 V reference with high accuracy is needed in an automotive environment. The SC-70-5 package offers a small footprint compared to larger alternatives. Ensure the design can accommodate the 15 mA maximum shunt current capability during peak load conditions.
Part Context
This device belongs to the TL4050 family of precision voltage references designed for low-power applications. The 'B' designation indicates the 0.2% accuracy grade, while 'Q' signifies automotive qualification. The 'DCKR' suffix identifies the SC-70-5 package and reel packaging configuration used for automated assembly processes.
Replacement Considerations
Consult official substitution guides for equivalent automotive-grade references. Verify pin compatibility and thermal performance when replacing with other series members.
