What is the Signal to Noise ratio of a 16 bit analog to digital converter (assuming all the noise is quantization noise and the converter range and input signal range are matched)?

Explanation / Answer

For ADC Signal to noise ratio (quantization) is defined as,

SNR (SQNR) = 20 x log10(2^n) dB.
wherer n = the number of quantization bits = 16.

SNR (SQNR) = 20 x log10(2^16) dB.
     = 20 x 16 x 0.30103 dB
     = 96.3296 dB
    
So,
The SNR of 16 bit ADC is 96.3296 dB.
