Dolby∗ B-C Type Noise Reduction System

Description

The CXA1560 series is a bipolar IC incorporating

stereo Dolby B-C type noise reduction (NR) system.

Five kinds of device are provided due to the

combination of three line output levels and two

packages for various applications.

A reduction in the number of external parts and

small package have been achieved due to the fact

that the spectral skewing circuits are all on-chip.
