Murray, Thank you very much for the datasheet. That confirms my suspicion about what was posted on eBay. For my application I actually need the 5V control voltage because I'm planning on using it with my Datum bc635PCI and TS2100. It's way too large for either unit but for the PCI card I can just mount it inside the PC case and run wires to the board for the rf out and control voltage. Both of these devices use the same dac/amp combination that puts out a 0.5 to 4.5 V control voltage. Does the MV89 really have a 5V EFC input? I suppose I could change out the opamp gain resistors to adjust the range.
