TL4050A41QDBZT

Overview

The TL4050A41QDBZT 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%. The device operates within a temperature range of -40 °C to +125 °C and features a maximum shunt current of 15 mA. It is housed in a compact SOT-23 package with three pins, designed for space-constrained applications requiring stable voltage regulation.

Feature Summary

• Provides high-precision voltage regulation with tight initial accuracy tolerances
• Operates effectively across extended industrial temperature ranges
• Designed for low-power consumption in micropower shunt configurations

Applications

• Portable battery-powered instrumentation systems
• Data acquisition channels requiring stable reference voltages
• Industrial process control signal conditioning circuits

Procurement Notes

Verify the specific suffix QDBZT against official Texas Instruments documentation to confirm automotive qualification status and packaging details. Ensure compatibility with design-in requirements before procurement. Cross-reference ordering information directly with manufacturer datasheets to avoid discrepancies in variant specifications.

Selection Notes

Select this component when a fixed 4.096 V reference is required with high initial accuracy. Consider the SOT-23 footprint for board space limitations. Evaluate thermal management needs given the operating temperature range. Compare power consumption characteristics against series reference alternatives if lower quiescent current is critical.

Part Context

This part belongs to the TL4050 family of precision voltage references from Texas Instruments. The family includes various output voltages and accuracy grades. The 'Q' designation typically indicates automotive qualification, while 'A' specifies the accuracy grade. The DBZT suffix denotes the specific SOT-23 package and tape-and-reel shipping configuration.

Replacement Considerations

Check for direct substitutes within the TL4050 series with matching voltage and accuracy. Verify pinout compatibility for SOT-23 packages. Confirm that alternative parts meet the same temperature and electrical performance standards.
