Head amplifier IC for CD-ROM drive (for 32 times speed or more)
s Overview
The AN8847SB is a head amplifier IC for
digital servo. It can configure an efficient CD-ROM
system in combination with the MN662753, and
allows a full-automatic adjustment of tracking bal-
ance-gain-offset and focus balance-gain-offset with
fewer external parts.
Built-in functions are a variable equalizer, high
band RF amp. and AGC which meet CAV playback
with 32 times speed or more.
