# Ideal ADC quantization-noise estimate
# Scope: Ideal uniform ADC quantization noise; full-scale uncorrelated error assumption.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

fullScale = 3.3 V
bits = 12

step := fullScale/2^bits [V]
noiseRms := step/sqrt(12) [mV]
idealSineSnrDb := 6.0206*bits+1.7609

check quantization noise budget: noiseRms <= 0.3 mV

scenario alternative: fullScale = 2.64 V
