Hi,

Should unused input pins be connected to GND or floating?

Best Regards,

    Hello Kuramochi-san,

    The unused input pins on ADS8168 can be left floating, and the device will still work correctly.  However, I recommend that the unused inputs are connected to GND to reduce the chance of noise coupling into the pins, possibly increasing the noise on the active input channel.
