I'm trying to find data on the Allen-Bradley FN507 decade voltage divider. A-B is now part of Rockwell Automation and I can't find anything related to their earlier passive components on their web site. Basically, I'm looking for a precision (+/- 0.01% to 0.1%, low TC) divider with a 9M/900K/90K/10K resistor chain for use in my PIC-based DAQ system using the LTC2400 24-Bit A/D. I want the divider on a common substrate rather than use discretes where the tolerance and TC's would have to be matched. I'm open to any other vendor. I've searched the web but I've had a hard time tracking down any decade voltage divider package other than complete units that are typically found in PMEL labs... Geesh, I should know where to find this sort of thing but I'm stuck. So many vendors have `changed hats'... Any help would be appreciated.
