TDA8808AT

INTEGRATED CIRCUITS DATA SHEET TDA8808T TDA8808AT Photo diode signal processor for compact disc players Product specification File under Integrated Circuits, IC01 November 1987 Philips Semiconductors Product specification Photo diode signal processor for compact disc players GENERAL DESCRIPTION TDA8808T TDA8808AT 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).
