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.
