Monolithic Linear IC

LA9242M

Analog Signal Processor (ASP)

for CD Players

Overview

Package Dimensions

unit:mm

The LA9242M is an analog signal processing and servo

control bipolar IC designed for use in compact disc players

; a compact disc player can be configured by combining

this IC with a CD-DSP such as the LC78922E and

LC78620E, with a small number of additional components

required. In addition, this IC allows CD-RW disk playback

due to the on-chip gain switching function.
