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.
