Monolithic Linear IC

LA9242M

Analog Signal Processor (ASP)

for CD Players

Overview

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.
