Hi Cooper,

Unfortunately by using a single-ended connection you would reduce output power by ~4. Differential signals have the property of using double of voltage output compared to single-ended.

You would need to filter the output of the Class-D with LC filter, and add series DC coupling capacitor to remove the bias in order to connect a single-ended load.

Hi Ivan:

thanks for your recommend ， about "with LC filter, and add series DC coupling capacitor " , can you give me related parameter or user guide files for speaker only has single end.

Hello Cooper,

There are no specific parameter recommendations for single ended but you can use the general recommendations in this app note: https://www.ti.com/lit/an/slaa701a/slaa701a.pdf.
