LA9230M Datasheet, PDF (1/20 Pages) Sanyo Semicon Device – Analog Signal Processor ASP for CD players

Ordering number: EN 5189
Monolithic Linear IC
LA9230M/9231M
Analog Signal Processor (ASP)
for CD players
Overview
The LA9230M and LA9231M are analog signal processing and
servo control bipolar ICs designed for use in compact disc
players; a compact disc player can be configured by combining
these ICs, a CD-DSP such as the LC78620E, and a small
number of additional components. The differences between the
LA9230M and the LA9231M are that the LA9231M: (1) has a
focus search time that is four times faster; (2) has an additional
capacitor pin for focus search smoothing; (3) and can disable
output of the track-kick signal during EF balance adjustment.
