I can't find any mention in the ADRF6516 datasheet about the input impedance of the GAIN pin. What is the input impedance of the GAIN pin? Can it be driven with a resistive divider / pot or must it be driven with a voltage source?
The gain pin is a high impedance pin so you should be able to drive it with a voltage divider or potentiometer.
Thanks jdobler - that's a great help.
