Dolby
B Type Noise Reduction System
Description
CXA1100, CXA1101, CXA1102 and CXA1163 are
ICs including two separate Dolby B type noise
reduction processors. Seven devices with four Dolby
levels and two types of package are provided for
various applications. These devices feature very few
external components, which is achieved by
integrated filter circuits using integrated thin film
capacitors with high capacitance.
