MN6475A
D/A Converter for Digital Audio Equipment
Overview
The MN6475A is a CMOS digital-to-analog converter
by noise shaping technology and is designed for PCM
digital audio equipment. It features a built-in 4 times
oversampling and 16-bit input digital filter.
It includes a digital de-emphasis circuit and analog post
filter to reduce the parts count and power consumption
of the overall D/A conversion system.
And also it includes two noise-shaping 1-bit D/A con-
verters, one each for the left and right channels.
