Dolby Btype 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.
