I'm looking for a way to control a potentiometer, or a resistor, or the gain of an op-amp, using a 0-3.3V analog DC control voltage. The resistor needs to behave like a resistor up to frequencies of about 1kHz, but of course more is better.
I've searched a bit and found a few parts that I might use but nothing that really stands out as an obvious choice. Seems like digital control is more common.
Any favorites?
