LM5064: the relationship between VAUXH and VCC

Part Number: LM5064

Hi,

In LM5064, we have VCC for power input and VAUXH for input measurement. 

What's the relationship between two pins? what's the acceptable voltage different?

Thanks.

    Hi Oliver,
    Apologies for the delay.. your post got missed..
    Vcc is the chip supply input and VAUXH is the select pin, connecting VAUXH =VCC sets the full voltage measurement b/n VCC to VEE pins.

    Best Regards,
