DAC is a Simulink model of a multi bit delta sigma digital to analog converter.
The DAC is based on a 9 bits set split in :
- 4 MSBs (bits : 8/7/6/5, respective weights : 32/16/8/4)
- 5 LSBs (bits 4/3/2/1/0, weights : 1/1/1/1/1)
The redundancy between bit#5 and LSBs allows two combinations to code a same value. Both combinations are used according to a hysteris cycle depending on the sign of the signal gradient (bit#5 is used if the signal increase while LSBs are used if the signal decrease).
