The IC provides three tone generators, a noise generator, four programmable attenuators and a mixer. It's a nice IC for microprocessor control (for all intents and purposes it cannot be used on a standalone basis). I don't have a pricelist handy, but small quantity pricing should still be less than $ 5.00. <> Larry Lippman @ Recognition Research Corp., Clarence, New York <> UUCP: {allegra|ames|boulder|decvax|rocksanne|watmath}!sunybcs!kitty!larry <> VOICE: 716/688-1231 {hplabs|ihnp4|mtune|seismo|utzoo}!/ <> FAX: 716/741-9635 {G1,G2,G3 modes} "Have you hugged your cat today?"
