For Audio Equipment 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 digi.

For Audio Equipment 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. Pin Assignment MA DIN LRCK BCK MB DVDD2 CKO DVSS2 M1 OUT1C N.C.

(See Table 1.) (See Table 1.) Note*1: This pin provides tristate output indicating the result of comparing the phases of the internal f s-rate-signal and the LRCK input signal. It is at "H" level when the LRCK signal leads and is at "L" level when the signal lags. At all other times, it is in the high-impedance state. MN35503 Operating Mode Descriptions Table 1-1.
