ICs for CD/CD-ROM Player
s
Overview
The AN8807SB is a head amplifier IC supporting the
digital servo.
Combination of this IC and the MN662710RA (digital
servo processor + signal processing + DAC/DF) allows
the rational CD ROM system to be constructed with small
number of external parts.
s
Features
Single supply operation
IV amplifier, tracking error amplifier, focus error ampli-
fier, RF amplifier and APC built-in
Detectors of DO, CROSS, OFTR and vibration built-in
Combination with the MN662710RA providing complete
automatic adjustment for tracking balance, tracking
gain, tracking offset, focus balance, focus gain and
focus offset
