LM4050QCEM3-10/NOPB

Voltage Reference Overview

The LM4050QCEM3-10/NOPB is an automotive-grade micropower shunt voltage reference manufactured by Texas Instruments. It provides a fixed output voltage of 10 V with an initial accuracy of 0.5%. The device features a temperature coefficient of 50 ppm/°C and operates within a junction temperature range of -40°C to +125°C. Packaged in a compact SOT-23-3 surface-mount case, it is qualified under the AEC-Q100 standard for automotive applications.

Voltage Reference Feature Summary

• Automotive qualification compliant with AEC-Q100 standards
• Micropower operation suitable for battery-powered systems
• High precision with low temperature drift characteristics

Voltage Reference Applications

• Automotive sensor signal conditioning
• Data acquisition systems requiring stable references
• Portable instrumentation circuits

Voltage Reference Procurement Notes

Verify the specific suffix 'QCEM3' against official Texas Instruments documentation to confirm the exact tolerance and package variant. Ensure the component meets AEC-Q100 requirements for your target automotive application. Cross-reference the datasheet revision date to ensure compatibility with current design specifications.

Voltage Reference Selection Notes

Select this component when a 10 V reference is required in space-constrained automotive designs. The SOT-23-3 package offers a small footprint compared to larger alternatives. Consider the 0.5% initial accuracy and 50 ppm/°C drift if higher precision than the standard LM4050 series is needed.

Voltage Reference Part Context

This part belongs to the LM4050 family of micropower shunt voltage references. The 'Q' prefix indicates automotive grade qualification, while 'CEM3' specifies the SOT-23 package and tape-and-reel packaging. The '-10' denotes the 10 V nominal output voltage option within the product line.
