Hi.

If I want to use a mono speaker with TLV320AIC3110, how should I connect it?
Please let me know the software settings as well.

Hello,

Figure 8-1 in the data sheet (Below) shows how two speakers are connected.

For the software settings, what would you like me to provide? Registers 0x20, 0x2A and 0x2B on Page 1 control the Class-D drivers.

Regards,

Aaron Estrada

Hi, Aaron

Thank you for your answer.

For mono speakers, do I connect them to Lch?

If the sound source is stereo, what registers should I set?

Hi,

It depends on the audio being sent but it is usually the left channel.

If the sound is stereo, there is not much to change. You need to look closely to register 63 on Page 0 as this register send the incoming audio data to the DACs. Here you can choose to send a specific channel to the DACs or a mono mix of both.
