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 realized on the chip with a

Switched Capacitor concept. Avoiding the use of

multipliers and non linear circuits a very high per-

formance in terms of noise suppression and total

harmonic distortion is
