ENOB


Effective number of bits (ENOB) is another way of specifying signal-to-noise and distortion ratio (SINAD). ENOB is calculated using the following formula:

Note  Assumes the full scale of the DAC is utilized.

The ENOB value is the value of an ideal DAC that is equivalent to the DAC of the device.
