1 / 6 page For Audio Equipment Overview The MN6474A is a CMOS digital-to-analog converter with a built-in 16-bit digital filter for pulse code modulation (PCM) digital audio equipment. It uses noise shaping technology to convert a digital signal into a PWM signal. It contains a 4-fold oversampling digital filter that permits simplification of the low pass filter after the D/A converter, thus greatly reducing the power consumption of the entire D/A conversion system. The chip provides both regular and inverted phase outputs for both channels. The chip contributes to cost and size reductions for CD players and other digital audio equipment. Features Built-in 4-fold oversampling digital filter (ripple of only ±0.0072 dB within the supported band and attenuation of 62.7 dB within the cutoff band) Internal resolution of 18 bits Two's complement input (I2S input code also supported) Built-in overflow limiter No zero cross distortion Sample-and-hold circuit is unnecessary Output pin for detecting zero input Single 5V power supply Applications CD players and other digital audio equipment MN6474A D/A Converter for Digital Audio Equipment Pin Assignment LRPOL LRCLK BCLK SRDATA DVSS3 DVDD 384FS PD MDATA MCLK 33 34 35 36 37 38 39 40 41 42 21 20 19 18 17 16 15 14 13 12 11 OUTR(–) AVSS1 AVSS2 OUTR(+) AVDD2 N.C.
