Notes:
(1) ATT_DATA
×
ATT transition time (Table 18, Table 19). For example, in Normal Speed Mode, this time is
1061/fs cycles (256/fs) at ATT_DATA=00H. ATT transition of the soft-mute is from 00H to FFH
(2) The analog output corresponding to the digital input has a group delay, GD.
(3) If the soft mute is cancelled before attenuating to -
after starting the operation, the attenuation is discontinued
and returned to ATT level by the same cycle.
