DESCRIPTION
The TDA7340 I
2
C bus controlled audio signal
processor contains all signal processing blocks of
a high performance car radio, including audio-
processor, stereodecoder, noise blanker, pause
detectorand differentmute functions.
The use of BICMOS technology allows the imple-
mentation of several filter functions with switched
capacitor techniques like fully integrated, adjust-
ment free PLL Loop filter, pilot detector with inte-
grator and two 19KHz notch filters.
This minimizes the number of external compo-
nents.
Due to a highly linear signal processing, using
CMOS-switching techniques instead of standard
bipolar multipliers, very low distortion and very
low noise are obtained also in the stereodecoder
part. The audioprocessor contains several new
features like softmute, zero-crossing mute and
pausedetector.
Very low Dc stepping is obtained by use of a
BICMOS technology.
