Hi!
Can the unused analog inputs AIN1 (pin 13) or AIN2 (pin 14) be left floating or do they need to be tied to ground with a capacitor or pull-down resistor? If so, what is the recommended component value (i.e. uF or ohms)?
According to the datasheet, it looks like AIN1 and AIN2 can be left floating but Register 50 may need to be configured (see page 79). I couldn't find anything about this in the EVM user's manual, and the AIN inputs seem to be used in the EVM schematic.
Thanks!
