COMPANDING
The WM8944B supports A-law and
-law companding on both transmit (ADC) and receive (DAC)
sides as shown in Table 46. Companding converts 13 bits (
-law) or 12 bits (A-law) to 8 bits using
non-linear quantization. This provides greater precision for low-amplitude signals than for
high-amplitude signals, resulting in a greater usable dynamic range than 8 bit linear quantization.
