DESCRIPTION
The TDA7338 is a new concept of monolithic inte-
grated stereo decoder with noise blanking for FM
car radio applications.
With the used BICMOS technique, the 19KHz
Notch Filter, the PLL Filter and Phase Filter is re-

alized on the chip with a Switched Capacitor con-
cept.
Avoiding the use of multipliers and non linear cir-
cuits a very high performance in terms of noise
suppression and total harmonic distortion is
reached.
