Texas Instruments ADC081C
ADC081C variants from Texas Instruments
ADC081C Overview
What changes between part numbers, and what to check before you lock the BOM — Analog to Digital Converters (ADC).
Key Features
- Footprint / package: TSOT, VSSOPLand pattern and thermal pad differ between these packages — run a quick footprint check before you swap variants.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 4 distinct suffix patternsExamples: 021CIMK/NOPB, 021CIMM/NOPB, 021CIMKX/NOPB, 021CIMMX/NOPB. Decode suffix meaning in the ordering notes under the variant table.
Target Applications
- Analog to Digital Converters (ADC) — 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

How to Choose the Right ADC081C Analog to Digital Converters (ADC)
Match the footprint first
Packages here: TSOT, VSSOP. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ADC081C, 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 "ADC081C" — include the full suffix (e.g. 021CIMK/NOPB, 021CIMM/NOPB, 021CIMKX/NOPB). RFQ with reel/tube preference and required date code.
