CMOS IC

Audio CODEC with Video Driver

LC07424LP

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.

Functions

Recording system

• ADC

: stereo single circuit, ∆∑Method 16bit,THD+N=-80dB(TYP, -1dBFS for input time)
