Texas Instruments ADC12C
ADC12C variants from Texas Instruments
ADC12C Overview
What changes between part numbers, and what to check before you lock the BOM — Analog to Digital Converters (ADC).
ADC12C is a Texas Instruments order-code family — not a single orderable MPN. This page lists 5 variants that share the same core device but differ in suffix fields (package, grade, reel/tube, electrical bin, etc.). Pick the exact full part number; substituting within the family without checking the datasheet often causes assembly or spec mismatches.
Operating Supply Voltage: 3.3V | Max Supply Voltage: 3.6V | Min Supply Voltage: 3V | Number of Channels: 1 | Number of Bits: 12 | Interface: Parallel | Max Operating Temp: 85°C | Min Operating Temp: -40°C Other listed variants describe: Package: 32-WFQFN Exposed Pad | Mounting Type: Surface Mount | Number of Bits: 12 | Operating Temperature: -40°C ~ 85°C; 12-Bit 80MSPS ADC, 1.0GHz BW, Diff Input, Parallel Int, 3.6V, 300mW.
Across listed variants, watch these parameters: packages: 32-WFQFN Exposed Pad.
Suffix examples in this family: 105CISQE/NOPB, 105CISQ/NOPB, 080CISQ/NOPB, 080CISQE/NOPB, 170CISQ/NOPB. The characters after the base number usually encode package, temperature, or performance grade — compare the variant table column-by-column rather than assuming pin-compatible drops-in.
Example MPNs: ADC12C105CISQE/NOPB, ADC12C105CISQ/NOPB, ADC12C080CISQ/NOPB, ADC12C080CISQE/NOPB, ADC12C170CISQ/NOPB.
Key Features
- Footprint / package: 32-WFQFN Exposed PadSingle package option across listed variants; still confirm reel vs tube suffix if you auto-insert.
- Lifecycle mix: ActiveConfirm lifecycle on the exact MPN, not just the base number prefix.
- 5 distinct suffix patternsExamples: 105CISQE/NOPB, 105CISQ/NOPB, 080CISQ/NOPB, 080CISQE/NOPB, 170CISQ/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

Ordering Code Differences
How suffixes on ADC12C map to package, grade, and reel options.
ADC12C uses a shared prefix; characters after the prefix encode orderable options. Two lines with the same prefix are not drop-in replacements unless the differing columns match your need.
Suffixes seen here: 105CISQE/NOPB, 105CISQ/NOPB, 080CISQ/NOPB, 080CISQE/NOPB, 170CISQ/NOPB.
Full MPN examples: ADC12C105CISQE/NOPB, ADC12C105CISQ/NOPB, ADC12C080CISQ/NOPB, ADC12C080CISQE/NOPB, ADC12C170CISQ/NOPB.
Tip: photograph or copy the reel label — reel diameter, QTY per reel, and moisture sensitivity level (MSL) are often suffix-driven and won't show in the schematic.
How to Choose the Right ADC12C Analog to Digital Converters (ADC)
Match the footprint first
Packages here: 32-WFQFN Exposed Pad. Open the land-pattern drawing before you substitute a different suffix.
Electrical headroom
Compare voltage and current columns in the variant table. For ADC12C, 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 "ADC12C" — include the full suffix (e.g. 105CISQE/NOPB, 105CISQ/NOPB, 080CISQ/NOPB). RFQ with reel/tube preference and required date code.
