Panasonic AN8808SB Datasheet
ICs for CD/CD-ROM Player
■ Overview
The AN8808SB is a head amplifier IC supporting the
digital servo (supporting the voltage output hologram
pick). Combination of this IC and the MN6627XX series
allows the rational CD system to be constructed with
small number of external parts.
■ Features
•
Single supply operation
•
I–V amplifier, tracking error amplifier, focus error amplifier, RF amplifier and APC built-in
•
Detectors of DO, CROSS, OFTR and vibration built-in
•
Combination with the MN6627XX series providing complete automatic adjustment for tracking balance, tracking gain, tracking offset, focus balance, focus gain and
focus offset
