TL4050A41QDCKR

Overview

The TL4050A41QDCKR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a nominal output voltage of 4.096 V with an initial accuracy of 0.1% and a temperature coefficient of 30 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, suitable for space-constrained designs requiring stable voltage references.

Feature Summary

• Delivers high-precision voltage regulation with tight initial accuracy tolerances
• Features low temperature drift characteristics for stable performance across wide thermal ranges
• Designed for micropower operation to minimize energy consumption in battery-powered systems

Applications

• Portable instrumentation requiring stable reference voltages
• Battery-operated measurement devices
• Data acquisition systems needing precise analog references

Procurement Notes

Verify the specific suffix 'Q' indicates automotive qualification status per official documentation. Confirm the 'R' suffix denotes reel packaging format. Ensure the SC-70-5 package outline matches your PCB footprint requirements. Check for RoHS compliance details in the latest datasheet revision. Validate that the 4.096V output aligns with your circuit design specifications before procurement.

Selection Notes

Select this component when a 4.096V reference with 0.1% accuracy is required in a small SC-70-5 package. Consider the 30 ppm/°C temperature coefficient for thermal stability needs. Evaluate the 15 mA maximum shunt current against your load requirements. Compare against other TL4050 variants if different voltage outputs or accuracy grades are needed.

Part Context

This part belongs to the TL4050 family of precision micropower shunt voltage references from Texas Instruments. The family offers various output voltages and accuracy grades in compact packages. The TL4050A series specifically targets applications requiring higher precision compared to standard industrial grade references. It serves as a key component in power management integrated circuits (PMIC) subsystems.

Replacement Considerations

Check for direct substitutes within the TL4050 family offering identical 4.096V output and 0.1% accuracy. Verify pin compatibility for SC-70-5 packages. Consider TL4050A41IDCKT for non-automotive equivalents if automotive qualification is not strictly required. Ensure temperature coefficients match system thermal constraints.
