[1] The circuit is DC adjusted at VP = ±12.5 V to ±30 V.
[2] With respect to SGND (0 V).
[3] 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 Figure 7.
[4] 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.
slope is directly related to
time-constant on the MODE pin
