Hi team,

we want to check how to deal with the unused channels. Float or pull down to GND?

    Hi Frank,

    1). You can power down this input through register 0x01.

    2). Also, you can leave these pins floating. Device powers down this channel since there is no signal.

    3). Alternatively, you can AC couple and then through 49.9-ohm resistor tie to GND.
