The problem is that I need to have a single analogue VDC output from a pair of VDC inputs. Both inputs are 'variable' +0 to 6VDC and with there returns to ground. I need to monitor the differential between inputs #1 and #2, where #2 will be either the same OR greater. This differential will be variable up to a maximum of +4VDC and will simply be read on a Voltmeter.
Whilst not being a total buffoon, I'm looking for absolutely the simplest solution to this, which might be a 'comparator', but I can't find one which says 'THIS ONE' in large enough, or simple enough letters for me..!
Any assistance with this frustrating issue would be truly appreciated.
