Overview

ICs for Compact Disc/CD-ROM Player AN8882SB Head amplifier IC for CD-ROM drive (for 32 times speed or more) s Overview The AN8882SB is a head amplifier IC for digital servo.
It can configure an efficient CD-ROM system in combination with the MN662754, and allows a full-automatic adjustment of tracking balance-gain-offset and focus balance-gain-offset with fewer external parts.
Built-in functions are a variable equalizer, wide band RF amp.
and AGC which meet CAV playback with 32 times speed or more.
