I need to multiply by 10 and 20, 670-2 can not multiply by 20. Thanks. Bert In a message dated 2/25/2011 8:03:55 A.M. Eastern Standard Time, [email protected] writes:
Well, I know Geraldo Lino de Campos on this list is using an ICS670-03 for this purpose. For me personally that part is too jittery by about a decade, but for your purpose it might just be the right compromise. Certainly has a friendlier package. datasheet: http://www.idt.com/products/getDoc.cfm?docID=18461996 Slight detour about soldering QFN's for prototyping. It is not /that/ bad. I will admit that when given the choice between QFNs and TSOPs I will pick the latter, but QFNs are do-able. All it takes is patience and a Can-Do attitude. Well, mainly patience really. ;) You can do those QFNs for example dead bug style on a solid copperclad ground plane. The trick then is to use aluminum foil to cover the pads you already soldered, and fluxfluxflux. You can put the decoupling caps real close in a sort of stonehenge around it. Like I said, requires a bit of patience, but it's fun when it actually works, plus you get better at it pretty fast. :) regards, Fred "Bert Kehren" wrote: > Thanks for the info Fred > The problem is the package.
