GENERAL DESCRIPTION
The TDA8808 is a bipolar integrated circuit designed for use in compact disc players with a single spot read-out system.
It amplifies the photo-diode signals and processes the error signals for the focus- and radial control network.

FEATUREs
• Data amplifier with equalizer and AGC
• Offset-free pre-amplifier with AGC for the servo signals
• Trackloss and drop-out detection
• Start-up procedure for focus
• Normalizing focus error output signal to minimize radial error interference
• Laser supply amplifier and reference source
• Both TDA8808T and TDA8808AT versions suitable for car, portable and home applications
• Single and dual supply application
• Focus in-lock signal; ready signal output (RD).
