Voltage Reference Procurement Notes

Verify the specific suffix 'Q' indicates automotive grade and 'EM3' denotes the SOT-23-3 package variant. Confirm the '-2.0' designation corresponds to the 2.048 V output version. Ensure compatibility with existing PCB footprints for SOT-23-3 components during integration.

Voltage Reference Selection Notes

Select this component when automotive certification is mandatory and a precise 2.048 V reference is required. It is suitable for designs needing low power consumption in space-constrained environments. Compare against other LM4050 variants if different voltage outputs or tolerance levels are needed.

Voltage Reference Part Context

This part belongs to the LM4050 family of precision micropower shunt voltage references. The 'Q' prefix signifies automotive qualification, while 'NOPB' indicates lead-free and RoHS compliance. It serves as a high-stability reference source for analog-to-digital converters and sensor interfaces in demanding environments.
