... Pb-free Package, which is Compliant with Requirements of RoHS 1. Description The U4468B is an integrated bipolar circuit for full multistandard sound IF signal pro- cessing 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 mod- ule for various applications ...
