Table 25. Power Limiter Registers (continued)
Distortion Limiter
The IC’s distortion limiter ensures that the speaker amplifier’s output does not exceed the programmed THD+N limit.
The distortion limiter analyzes the Class D output duty cycle to determine the percentage of the waveform that is
clipped. If the distortion exceeds the programmed threshold, the output gain is reduced.
