Ultralow Distortion Audio Panpot Amplifier
An audio "panpot" circuit continuously varies the position of a monophonic audio signal between left and right channels in response to a potentiometer setting. This circuit can be built discretely, but integrating the amplifiers and resistors on a single chip offers improved specifications, less PCB area, and lower production cost. The AD8273 dual low-distortion difference amplifier uses on-chip gain-setting resistors to ensure excellent matching.

Please tell me where to buy a 0.1% tolerance Potentiometer.
Otherwise this circuit is worthless.
I can use a standard dual op-amp and make-up the gain elsewhere.
