Table 56. DAC Digital Volume Level Setting
2. DAC Soft Mute
The DAC block has a digital soft mute circuit. The soft mute operation is performed at digital domain.
The output signal is attenuated to -∞ in “ATT setting level x ATT transition time” from the current DAC
digital volume setting level by setting DA1MUTE bit, DA2MUTE bit or DA3MUTE bit to “1”. When the
DA1MUTE bit, DA2MUTE bit or DA3MUTE bit returns to “0”, the mute is cancelled and the output
attenuation level gradually changes to ATT setting level in “ATT setting level x ATT transition time”. If the
soft mute is cancelled before attenuating to -∞ after starting the operation, the attenuation is
discontinued and the volume level returns to original volume setting level by the same cycle. The soft
mute is effective for changing the signal source without stopping the signal transmission.
The attenuation level transition takes 924/fs from 0dB to -∞ and from -∞ to 0dB. Soft mute function is
available when each DAC is in operation. The attenuation value is initialized by setting the PDN pin = “L”.
