× 110 W class-D power amplifier

11. Static characteristics

[1]

[2]

With respect to SGND (0 V).

[3]

The transition between Standby and Mute mode has hysteresis, while the slope of the transition between Mute and Operating mode is

determined by the time-constant of the RC network on pin MODE; see Figure 8.

[4]

DC output offset voltage is gradually applied to the output during the transition between the 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.
