I was thinking the other day that if you got a precision voltage to current converter like the AD650;

It would be quite easy to make a high resolution digital voltmeter by feeding the output of the VFC into a frequency counter. For example with the AD650 with linearity of 0.002% up to 10Khz, equivalent to the resolution a 50 000 count voltmeter. It would require precision input switching, etc. But still a whole lot cheaper than buying a meter with this resolution. Obviously you need to have via frequency counter with at least 5 digits resolution.
Any thoughts???
