The circuit is DC adjusted at V
With respect to SGND (0 V).
The transition between Standby and Mute mode contain hysteresis, while the slope of the transition between Mute and Operating mode
is determined by the time-constant on the MODE pin; see
DC output offset voltage is applied to the output during the transition between Mute and Operating mode in a gradual way. The slope of
the dV/dt caused by any DC output offset is determined by the time-constant on the MODE pin.
