LM4050AEM3X-4.1/NOPB

Voltage Reference Overview

The LM4050AEM3X-4.1/NOPB 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% and a temperature coefficient of 50 ppm/°C. The device operates within a junction temperature range of -40°C to +125°C and supports a maximum cathode current of 15 mA. Packaged in a compact SOT-23-3 surface-mount case, it draws a typical quiescent current of 78 µA. This component belongs to the LM4050 series and is designed for applications requiring stable reference voltages in space-constrained environments.

Voltage Reference Procurement Notes

Verify the complete part number including suffixes such as NOPB and packaging options like reel or cut tape. Confirm RoHS compliance status and ensure the specific grade matches application requirements. Check for any recent product change notifications that may affect pinout or specifications before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a 4.096 V reference with 0.1% accuracy is required in a small SOT-23-3 package. Consider the 50 ppm/°C temperature coefficient for thermal drift analysis. Ensure the circuit design allows for sufficient cathode current to maintain regulation without exceeding the 15 mA maximum limit during operation.

Voltage Reference Part Context

This part is a member of the LM4050 family of micropower shunt voltage references from Texas Instruments. The family offers various fixed output voltages and accuracy grades. The 'A' designation typically indicates higher precision compared to standard variants. The 'Q' suffix denotes automotive qualification under AEC-Q100 standards, though this specific 'A' variant focuses on general precision applications.
