For Audio Equipment MN64782 D/A Converter for Digital Audio Equipment Overview Pin Assignment The MN64782 is a CMOS digital-to-analog converter with a built-in 8-fold oversampling digital filter for pulse code modulation (PCM) digital audio equipment. It uses noise shaping technology to convert a digital signal into a PWM signal. The D/A converter uses a switched capacitor to eliminate sensitivity to clock jitter.
