In order to achieve low power consumption in PCM audio systemns capable of reproducting high-quality sound at the low tape speed used by the 8 mm Video, there is a need for 10 bit/15 ¿sec A/D and D/A converters made by CMOS technology. The converters have an additional advantage in that they are inexpensive to produce.
