What is SINAD?

SINAD (Signal-to-Noise and Distortion Ratio) is a measure of the quality of an analog-to-digital converter (ADC). It represents the ratio of the desired signal power to the sum of all other components of power in the system, including noise and harmonic distortion.

What is ENOB?

ENOB (Effective Number of Bits) is a measure of the resolution of an ADC, taking into account all imperfections. It represents the number of bits of a perfect ADC that would have the same signal-to-noise ratio as the actual ADC.

How to use the calculator

  1. Enter the SINAD value in dB in the input field.
  2. Click the "Calculate" button to compute the ENOB.
  3. The ENOB value in bits will be displayed in the results section.

Example Calculation

If an ADC has a SINAD of 80 dB, the ENOB can be calculated as:

ENOB = (80 - 1.76) / 6.02 = 12.86 bits

This means the ADC has approximately 12.86 bits of effective resolution.

Principle of Conversion

The relationship between SINAD and ENOB is based on the following formula:

ENOB = (SINAD - 1.76) / 6.02 dB

This formula is derived from the fact that each bit of resolution adds approximately 6.02 dB to the SINAD.
