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 MN35502 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-tonoise ratio.

The MN35502 chip makes a major contribution to reducing thecost and size of CD players and other digital audio equipment.
