U4488B
Quasi-Split Sound Circuit and AM Demodulator
Description
The U4488B is an integrated bipolar circuit for full multistandard sound IF signal processing in TV/VTR and Multimedia applications.
It supplies AM signals as well as FM/NICAM sound IF signals and thus allows the design of a universal sound IF module for various applications.
The U4488B has the same performance like the U4468B, with the additional feature of a second symmetrical IF input.
