Example of Schematic to be used, resistors (1k ?) to the adjusted midpoint (+/-) at inputs within 20 or 40 mV (scale). Depends on the joystick used (100 Ohm ?).

*EDIT: these resistors are not needed if you don't care about **Common Mode input voltage** : min=AGND+1.2V and max=AVDD-1.3V.* If used, then take **same resistors** from the same "lot", and "paired" if possible.

Using the two inputs (A and B) let one use an x-y joystick, just mounting 2 pots in parallel.
