Hi, i like to have a voltage controlled resistor,
i am looking in the LM13700 datasheet,
there is a single ended resistor schematic
and there is a dual ended schematic.
I dont understand what is a single ended resistor ?
And the schematic is not clear to me, is the input at the + input ?, and the Vout is behind a capacitor ?, why is that ?
I will try the dual ended resistor, will it give exact the same voltage at the output, or will is be different somehow ?
thanks
