This tool calculates **Effective Number of Bits **(ENOB) in an Analog-to-digital converter (ADC). It uses the dB value of **Signal Noise and Distortion** (SINAD) and the formula:

**ENOB _{bits} = (SINAD_{dB} – 1.76)/6.02**

**Calculator**

**Example Calculation**

For a SINAD of 60 dB, the ENOB is equal to 9.67.

Let’s take a look at the data sheet for a practical ADC.

Using the SINAD value of **72.2 dB**, we get **11.7 effective bits**. This value is consistent with the table above.
