"WebAudio bit depth. 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. " - Dac dithering

Squeeze 10-Bit Performance From An 8-Bit DAC - Electronic Design

WebThe DAC sampling capacitance is only 1pF from b15-b12 and b12r, which greatly eases the input driver and reference buffer requirements. Three redundant capacitors (b12r, b8r, b4r) are included to tolerate decision errors [22], [23] from the flash sub-ADC and earlier bit trials. WebMay 1, 2024 · where the C i is the ith capacitor in the DAC, G is the inter-stage gain, C t is the total capacitor in the DAC and V ref is the reference voltage.
