DESCRIPTION
The TDA7449 is a volume tone (bass and treble)
balance (Left/Right) processor for quality audio
applications in TV systems.
Selectable input gain is provided. Control of all
the functions is accomplishedby serial bus.
The AC signal setting is obtained by resistor net-
works and switches combined with operational
amplifiers.
Thanks to the used BIPOLAR/CMOSTechnology,
Low Distortion, Low Noise and DC stepping are
obtained.
