LC07422T
CMOS IC
Audio CODEC with Video Driver
Overview
The LC07422T is an audio CODEC that has a built-in speaker amplifier and headphone amplifier and incorporates a
video driver.
A 2-input line selector and ALC circuit are provided in the audio recording system.
A speaker amplifier with EVR, headphone 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 video driver obviating the need for an output coupling capacitor is included.
• 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
• The input signals for the speaker amplifier and headphone amplifier can be selected (DAC or PGA output).
• Power-down control of individual function block and be exercised.
• COCEC
ADC for the digital recording of analog input signals
DAC for outputting analog signals from the digital playback data
• De-emphasis filter
• When Y/C video signals are input, composite signals can be generated, and 3-system driver signals can be output.
