There are MANY kinds of A/D converters for MANY KINDS of jobs. The specs you quote mean very little without defining what they are. Bandwidth, for example. Is this intended to be the maximum bandwidth? Or the ONLY bandwidth allowed for the incoming analog signal? Or is it some other bandwidth for some other parameter of the device? If it represents the bandwidth of the incoming analog signal, that A/D converter wouldn't be suitable for high-quality digital music from an analog source.
