Part Number: TLV320AIC3111
Other Parts Discussed in Thread: DRV135

hello

The DAC being developed requires Left and Right 1/4" Unbalanced output and XLR Balanced out.

I'm using TLV320AIC3111.

Is there any way to use Balanced Speaker output as LINE output?

I want to connect the DAC output to an audio interface rather than a speaker. Is this possible?

Hi,

The class-AB can be used for LINEOUT as shown below.

Regards.

thank you for answering.

I know the part you mentioned, but I inquired because I needed a balanced line out.

Do not use external Audio Balanced Line Drivers such as DRV135.

Thank you

You have to filter out the high switching frequency of the class-D maybe through a RC filter and then adjust the class-D gain so that your speaker output is not exceeding the line input requirement.
