With respect to SGND (0 V).
The transition between Standby and Mute modes has hysteresis, while the slope of the transition between Mute and Operating modes is
determined by the time-constant of the RC network on pin MODE; see
DC output offset voltage is gradually applied to the output during the transition between Mute and Operating modes. The slope caused
by any DC output offset is determined by the time-constant of the RC network on pin MODE.
