A built-in low-cost low-resolution dithering DAC is employed to compensate ana-log outputs of the on-chip DAC for higher resolution and linearity. Simulation shows that using a 6-bit dithering DAC a 14-bit on-chip DAC could be calibrated with 2-bit ENOB gain.

An analog signal (in red) encoded to 4-bit PCM digital samples (in blue); the bit depth is four, so each sample's amplitude is one of 16 possible values. In digital audio using pulse-code modulation (PCM), bit depth is the number of bits of information in each sample, and it directly corresponds to the resolution of each sample.
