ADC1206S040/055/070
Single 12 bits ADC, up to 40 MHz, 55 MHz or 70 MHz
S = slope of the ideal straight line = code width; i = code value.
13.1.2
Differential Non-Linearity (DNL).
It is the deviation in code width from the value of 1 LSB.

s
= M/N, where M is the number of cycles and N is number of
samples, M and N being relatively prime), and digitized by the ADC under test.
Remark:
in the following equations, P
noise
is the power of the terms which include the
effects of random noise, non-linearities, sampling time errors, and “quantization noise”.
13.2.1
Signal-to-noise and distortion (SINAD)
The ratio of the output signal power to the noise-plus-distortion power for a given sample
rate and input frequency, excluding the DC component:

13.2.2
Effective Number Of Bits (ENOB)
It is derived from SINAD and gives the theoretical resolution an ideal ADC would require
to obtain the same SINAD measured on the real ADC. A good approximation gives:
