TL4050A41QDBZR

Overview

The TL4050A41QDBZR is a precision micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 4.096 V with an initial accuracy of ±0.1%. The device features a temperature coefficient of 50 ppm/°C and supports a maximum shunt current of 15 mA. It operates within a junction temperature range of -40°C to +125°C and is housed in a compact SOT-23-3 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with ±0.1% initial accuracy for critical analog signal integrity.
• Optimized for low-power applications through micropower quiescent current consumption.
• Engineered for automotive environments with AEC-Q100 qualification and extended industrial temperature stability.

Applications

• Automotive sensor signal conditioning circuits
• Data acquisition systems requiring stable reference voltages
• Portable battery-powered instrumentation

Procurement Notes

Verify the specific suffix 'Q' confirms AEC-Q100 automotive qualification status. Confirm the 'R' suffix indicates reel packaging configuration. Ensure the 'A' grade matches the required ±0.1% accuracy specification for your design. Cross-reference the full part number against the manufacturer's latest datasheet to confirm active production status and any recent package or marking changes.

Selection Notes

Select this component when designing for automotive-grade reliability combined with high DC accuracy. The SOT-23-3 package offers space efficiency for dense PCB layouts. Consider the 50 ppm/°C temperature coefficient for thermal stability requirements. Evaluate the 15 mA maximum shunt current against load demands to ensure adequate noise filtering capability without exceeding power dissipation limits.

Part Context

This device belongs to the TL4050 family of precision shunt references from Texas Instruments. The family includes various output voltages and accuracy grades, such as the TL4050B series with ±0.2% accuracy. The TL4050A41 variant specifically targets applications needing 4.096 V output with tighter tolerance than standard commercial parts.

Replacement Considerations

Compatible substitutes include other AEC-Q100 qualified shunt references from Texas Instruments, such as the TL4050B41QDBZR (±0.2% accuracy) or TL4050C41QDBZR (±0.5% accuracy). Verify pinout compatibility and thermal performance before substitution.
