ADC Resolution: Bits vs Discrete Levels
How an analog-to-digital converter's resolution (in bits) maps to the number of discrete quantization levels (2^N), with typical uses.
| Resolution (bits) | Discrete levels (2^N) | Typical use |
|---|---|---|
| 8-bit | 256 | Consumer, displays |
| 10-bit | 1,024 | General control |
| 12-bit | 4,096 | Sensing, data acquisition |
| 14-bit | 16,384 | Precision measurement |
| 16-bit | 65,536 | Audio, precision instruments |
| 24-bit | 16,777,216 | High-end audio, metrology |
Method & sources
Levels = 2^(bits), a mathematical definition. Typical uses are common industry practice, not strict rules.
