MN35503
D/A Converter for Digital Audio Equipment
Overview
The MN35503 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 incorporating an 8-fold oversampling digital
filter that eliminates a low-pass filter after the D/A
converter and greatly reduces the power consumption of
the overall D/A conversion system.
The chip makes a major contribution to reducing the
cost and size of CD players and other digital audio
equipment.
