Overview
The MN35502 is a CMOS digital-to-analog converter
designed especially for PCM digital audio equipment. It
features a built-in digital filter with 16/20-bit input.
It uses pulse edge modulation (PEM) and JVC advanced
noise shaping (VANS) to yield the high resolution and
low distortion ratio equivalent to those of 20-bit systems
covering the range between 0 and 20 kHz.
The chip incorporates an 8-fold oversampling digital
filter that eliminates a low-pass filter after the D/A
converter and thus greatly reduces the power consumption
of the overall D/A conversion system.
Use of single-channel 4PEM output yields a D/A
converter with a low distortion ratio and high signal-to-
noise ratio.
The chip makes a major contribution to reducing the
cost and size of CD players and other digital audio
equipment.
