Texas Instruments ADC122S
ADC122S variants from Texas Instruments
ADC122S Overview
What changes between part numbers, and what to check before you lock the BOM — Analog to Digital Converters (ADC).
Key Features
- Footprint / package: MSOP, 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 10-TFSOP, 10-MSOP (0.118", 3.00mm Width)Land 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.
- 6 distinct suffix patternsExamples: 021CIMM, 101CIMM/NOPB, 655CIMMX/NOPB, 051CIMMX/NOPB, 625CIMM/NOPB (+1 more). 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 ADC122S Analog to Digital Converters (ADC)
Match the footprint first
Packages here: MSOP, 8-TSSOP, 8-MSOP (0.118", 3.00mm Width), 10-TFSOP, 10-MSOP (0.118", 3.00mm Width). Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ADC122S, 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 "ADC122S" — include the full suffix (e.g. 021CIMM, 101CIMM/NOPB, 655CIMMX/NOPB). RFQ with reel/tube preference and required date code.
