TL4050A41QDCKT

Overview

The TL4050A41QDCKT 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 30 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 compact SC-70-5 surface-mount package.

Feature Summary

• Delivers high-precision voltage regulation with 0.1% initial accuracy for sensitive measurement circuits.
• Optimized for low-power applications through micropower consumption characteristics.
• Ensures stable performance across wide industrial temperature ranges with low temperature drift.

Applications

• Portable battery-powered instrumentation requiring precise voltage references
• Data acquisition systems needing stable analog-to-digital converter references
• Industrial process control loops utilizing shunt regulation

Procurement Notes

Verify the specific suffix QDCKT against the official datasheet to confirm package type, tape-and-reel quantity, and automotive or industrial grade designation. Ensure compatibility with existing PCB footprints for the SC-70-5 package. Confirm end-of-life status if long-term supply is required, as availability may be limited compared to active series members.

Selection Notes

Select this component when a 4.096 V reference with tight 0.1% tolerance is required in a minimal footprint. Compare against the TL4050C series if higher noise or looser accuracy is acceptable for cost reduction. Verify that the 15 mA maximum shunt current meets the load requirements of the target circuit design.
