Except Shutdown Mode, TAS5828M has other 4 states for different power dissipation which listed in the Electrical Characteristics Table.
- Deep Sleep Mode. Register 0x03h -D[1:0]=00, Device stays in Deep Sleep Mode. In this mode, I2 C block keep works. This mode can be used to extend the battery life time in some portable speaker application case, once the host processor stopped playing audio for a long time, TAS5828M can be set to Deep Sleep Mode to minimize power dissipation until host processor start playing audio again. Device returns back to Play Mode by setting Register 0x03h -D[1:0] to 11. Compare with Shutdown Mode (Pull PDN Low), enter or exit Deep Sleep Mode, DSP keeps active.
- Sleep Mode. Register 0x03h -D[1:0]=01, Device stays in Sleep Mode. In this mode, I2 C block, Digital core, DSP Memory , 5 V Analog LDO keep works. Compare with Shutdown Mode (Pull PDN Low), enter or exit Sleep Mode, DSP keeps active.
- Output Hiz Mode. Register 0x03h -D[1:0]=10, Device stays in Hiz Mode. In this mode, Only output driver set to be Hiz state, all other block work normally.
- Play Mode. Register 0x03h -D[1:0]=11, Device stays in Play Mode.
