CXA1550P, CXA1551M/P CXA1552M/P, CXA1553M/P Dolby B∗ type Noise Reduction System Description The CXA1550/CXA1551/CXA1552/CXA1553 are bipolar ICs providing two separate Dolby B type noise reduction processors. The series is composed of seven devices having four Dolby levels and two types of package for various applications. These devices feature very few external components, which is achieved by monolithic filter circuits using integrated thin film capacitors with high capacitance.
