TL4050B41QDBZR

Overview

The TL4050B41QDBZR 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 ±0.2%. The device features a temperature coefficient of 50 PPM/°C and supports a maximum shunt current of 15 mA. It operates within a temperature range of -40°C to +125°C and is housed in a SOT-23-3 surface-mount package.

Feature Summary

• Provides stable precision voltage reference suitable for high-accuracy analog circuits
• Designed for micropower applications with low quiescent current consumption
• Automotive-grade qualification ensures reliability under harsh environmental conditions

Applications

• Automotive sensor signal conditioning
• Data acquisition systems requiring precise voltage references
• Battery management system monitoring circuits

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and automotive qualification status. Confirm RoHS compliance and specific tape-and-reel specifications required for automated assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a 4.096 V reference with ±0.2% initial accuracy is required in an automotive environment. Ensure the application can accommodate the SOT-23-3 package dimensions and that the thermal operating range aligns with the specified -40°C to +125°C limits.

Part Context

This component belongs to the TL4050 family of precision shunt voltage references. The 'Q' designation indicates automotive qualification, while 'B' specifies the ±0.2% accuracy grade. The '41' suffix denotes the 4.096 V output voltage option within this product line.

Replacement Considerations

Compatible substitutes include TL4050A41QDBZR for higher accuracy or TL4050C41QDBZR for standard accuracy. Non-automotive equivalents like TL4050B41IDCKR may be considered if automotive qualification is not required.
