It looks to me like the HV5812 is really designed to be a HV source driver (Like for VFD's?), whereas the HV5522 is a sink driver. (Disclaimer: I know nothing about these chips apart from what I've gleaned of the datasheets in a handful of minutes.) :D
Sure, Jens. I'll email you directly with the postage/paypal information. -Adam On Mon, Feb 21, 2011 at 1:32 PM, jb-electronics <webmas...@jb-electronics.de > wrote: > Hi, > > that makes sense, but I guess you would still run into trouble when trying > to drive ZM1040 at 4.5mA..
