From article <7070002@hpnmdla.HP.COM>, by sheppard@hpnmdla.HP.COM (Roger Sheppard): > Yes this sounds like delta modulation but that is not new. The only recent > anouncement that concerns a 1 bit D/A is from Phillips addressing the Crystal Semiconductor in Austin, (512) 445 7222, manufactures several very interesting A/D converters, in case anyone is interested. One is a two-channel 16-bit Delta Sigma converter designed specifically for digital audio. Very nice parts, and I believe they go for around $100 quantity one. The "sample and holds," anti-aliasing and decimation filtersand voltage reference are all built in (28-pin package). -- Jon R.
