[sdiy] Single-supply operation of a SSM2164 VCA/MLT04 analog multiplier?

[harrybissell]

Is it cheating to generate the negative supply ?  There are many charge pump
converters (Intersil 7660 for example... and many from Maxim ... max680 iirc)
that could generate a negative supply.

I just used one of these for a DAC application on a battery powered unit... this
allowed
me to guarantee that zero would REALLY be zero...
