7.2.1.3 Application Curve

The effective number of bits (ENOB) is often used to compare the performance of ADCs and ΔΣ modulators. Figure 7-3 shows the ENOB of the AMC3306M25-Q1 with different oversampling ratios. By using Equation 3, this number is also calculated from the SINAD:

Equation 3. SINAD = 1.76dB + 6.02dB × ENOB
