Product specification

TDA8809T

GENERAL DESCRIPTION

The TDA8809T is a bipolar integrated circuit which provides control signals for the radial motor. These control signals

are generated from radial error signals received from a photo-diode signal processor (TDA8808), and velocity control

signals from the control processor.

Features

• Tracking error processor with automatic asymmetry control

• AGC circuity with automatic start-up and wobble generator

• Tracking control for fast forward/reverse scan, search, repeat and pause functions

• Radial polarity - 4 - tracks counting

• Possibility for car, home and portable applications.
