LSB Size vs ADC Bits
Formel
## 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.
Lösungsbeispiel
12-bit ADC with 3.3 V reference.
- 01Levels = 2^12 = 4096
- 02LSB = 3.3 / 4096 = 0.000806 V = 0.806 mV
- 03Dynamic range = 20 x log10(4096) = 72.2 dB
Häufig Gestellte Fragen
What is ENOB?
Effective Number of Bits accounts for real-world noise and distortion. A 12-bit ADC might have 10.5 ENOB due to noise.
Does higher resolution mean better accuracy?
Not necessarily. Accuracy depends on reference voltage precision, linearity errors, and noise floor.
How does sampling rate relate to resolution?
They are independent specifications. Oversampling can trade speed for effective resolution (averaging).
