Description

The TDA7449L is a volume control and balance (Left/Right) processor for quality audio applica-
tionsin TVsystems.
Selectable input gain is provided. Control of all thefunctionsis accomplishedby serialbus.
The TDA7449L AC signal setting is obtained by resistor net-works and switches combined with operational amplifiers.
Thanksto theusedBIPOLAR/CMOSTechnology,
Low Distortion, Low Noise and DC stepping are obtained.
