I want to use an LM13700 as a voltage controlled resistor, and I want it to act like a rheostat. When will it act non-linearly?
The description of this circuit is on page 15 of the datasheet, and the circuit diagram is on page 16, figure 28.
I intend to use two of them to produce a variable voltage divider for an audio signal. I am worried that the resistance might vary with regards to frequency, temperature etc.
