DESCRIPTION
The TDA7344 is a volume tone (bass and treble)
balance (Left/Right) processor for quality audio
applications in car radio and Hi-Fi systems.
It reproduces surround sound by using phase
shifters and a signal matrix. Control of all the
functionsis 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.
