The ALC limiter’s target level can also be set for a predetermined maximum output power or voltage level. This

method of ALC limiter operation is known as “power limit” mode. Operating the ALC limiter in “power limit” mode

prevents the speaker or headphone from playing at unsafe hearing levels that can permanently damage the end

user’s ears. “Power limit” operation is especially useful for applications such as listening to music through a set of

headphones. Another benefit of using the ALC limit in “power limit” mode is to extend battery life by reducing

power consumption of the output amplifiers during audio playback.
