The following web site describes a circuit that utilizes a 6201 twin triode for common grid IV conversion:http://ultranalog.com/cdenhancer/cdenhancer1.html
(please see figure 2)
The DAC appears to be connected to the analog circuit using a 1 volt source between the digital ground and analog ground, the idea being that the DAC sees 0V.
But what is this 1V source? It appears to be a battery symbol, but I don't believe the circuit would function with a battery connecting the analog to digital ground.
Can someone please elaborate on what this voltage source might be?
Thanks!
