D/A Converter for Digital 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 (I
2
S 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
