## ADC Resolution
### Formulas
**LSB = V_ref / 2^N**
**Levels = 2^N**
**Dynamic Range = 20 x log10(2^N) dB**
N is the number of bits. Each additional bit doubles the resolution and adds 6 dB of dynamic range.

计算示例
12-bit ADC with 3.3 V reference.
- Levels = 2^12 = 4096
- LSB = 3.3 / 4096 = 0.000806 V = 0.806 mV
- Dynamic range = 20 x log10(4096) = 72.2 dB
