TPA6140A2: Using only right channel (INR– & INR+)

Part Number: TPA6140A2

Hi team,

I would like to confirm if it is okay to leave the pins of INL– & INL+ (Left channel) floating as the customer would like to use only the Right channel of TPA6140A2?

Thanks!

Jonathan

    Hi Jonathan,

    It is OK to leave these pins open if not used. Other option would be to AC couple them to GND.

    You should also make sure that HP_EN_L bit is set to 0 so that amplifier is disabled and not consuming idle curent.

    Best regards,
