What are the maximum I/O voltages that the MAX11300 PIXI technology supports?

PIXI devices can support between -10V and +10V provided the supply voltages VAVDDIO and VAVSSIO are set to +12V and -12V, respectively. VAVDDIO (and VAVSSIO) must be set, at minimum, to the value of the largest positive and negative voltage driven by any of the ports set in those modes. For improved linearity, it is recommended to set VAVDDIO 2.0V above the largest voltage value and to set VAVSSIO 2.0V below the lowest voltage value.
