LA9240M
Analog Signal Processor (ASP)
for CD players
Overview
The LA9240M 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 LC78622E and LC78620E, with a small
number of additional components required.
