The SA DAC uses multi-level D/A conversion, illustrated here. Like
multi-bit conversion, the multi-level system uses many switches
operating in parallel. Unlike multi-bit designs, the value of all switches is
identical—a binary 1.
The output of the multi level D/A converter varies from 0 to 64,
depending on the number of switches set to On for each sample.
