TDA8808AT - NXP

TDA8808AT Photo diode signal processor for compact disc players

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 signal.
