Analog Devices LM4050CEM
LM4050CEM variants from Analog Devices
LM4050CEM Overview
What changes between part numbers, and what to check before you lock the BOM — Voltage References.
Key Features
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 2 distinct suffix patternsExamples: 3-4.1+T, 3-5.0+T. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Voltage References — design-in and field replacement
- BOM scrub where only the base prefix is known but suffix is TBD
- Second-source checks when the original MPN is constrained
Ordering Variants
Compare 2 LM4050CEM part numbers by package, electrical parameters, lifecycle, and availability. Use RFQ for stock and lead-time confirmation.
| Part Number | Description | Manufacturer | Lifecycle | RoHS | Availability | Action |
|---|---|---|---|---|---|---|
| LM4050CEM3-4.1+T | IC VREF SHUNT 4.096V SOT23 | Analog Devices | Active | Compliant | In Stock | |
| LM4050CEM3-5.0+T | IC VREF SHUNT 5V SOT23-3 | Analog Devices | Active | Compliant | In Stock |

How to Choose the Right LM4050CEM Voltage References
Match the footprint first
Pull the exact package drawing for your MPN — base-number swaps fail most often at the footprint, not the schematic.
Electrical headroom
Compare voltage and current columns in the variant table. For LM4050CEM, a suffix with lower voltage or current rating will not survive the same circuit without recalculation.
Temp grade letter matters
Commercial (0–70 °C) and industrial (−40–85 °C+) suffixes look similar in the prefix — confirm ambient + self-heating, not just the first page of the datasheet.
Copy the full MPN
Do not BOM only "LM4050CEM" — include the full suffix (e.g. 3-4.1+T, 3-5.0+T). RFQ with reel/tube preference and required date code.
