MN6460A

( DataSheet : www.DataSheet4U.com ) For Audio Equipment MN6460A A/D Converter for Digital Audio Equipment Overview The MN6460A is a 16-bit CMOS analog-to-digital converter designed especially for PCM digital audio equipment. It features a built-in digital filter. It uses noise shaping to convert an analog signal to a 16-bit digital signal. Incorporating digital filter permits simplification of the analog filter that normally precedes the A/D converter, thus greatly reducing the power consumption of the overall A/D conversion system. Pin Assignment Features Analog and digital-mixed CMOS LSI A/D conversion using noise shaping 64-fold oversampling Built-in digital filter Sample and hold circuit is unnecessary Serial output using two's complement code Built-in offset compensation circuit Built-in overflow limiter Single 5-volt power supply (when V REF =1.5 V and AG=2.5 V) DVDD LR–POL I–E LR–CLK B–CLK CLR OFCLR N.C.
