LC07424LP ^{Audio CODEC with Video Driver}
Overview
The LC07424LP is an audio CODEC that has a built-in speaker amplifier and Line amplifier and incorporates a video
driver.
A input line selector and ALC circuit are provided in the audio recording system.
A speaker amplifier and line output are provided in the playback system. A video driver that obviates the need for an
output coupling capacitor is also included to enable AV playback processing with the single chip.
Features
• Audio systems can be configured using this single chip since almost all the audio system circuits are provided.
• A high-performance ALC/limiter circuit that meets a variety of different conditions is incorporated.
• A wide range of different functions can be set using parameter settings.
