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.
