TLV320AIC34: Single-end output by Line output pins

Part Number: TLV320AIC34

Hi,

Can each line output plus pins(i.e. LEFT_LOP_A) be used as singled-end output?

Then, should each minus pins(i.e. LEFT_LOM_A) be left open?

Best Regards,

Hello Kuramochi-san,

Apologies for the delay in response. I see there is a previous post by you asking a similar question and assume they are related. If they are, I will close the other one.Please let me know.

To answer your question, the Lineouts (LEFT/RIGHT_LOP/M) are only used as fully differential outputs. The headphone outs, HPLOUT, HPLCOM, HPROUT, and HPRCOM can be used as SE outputs.

Regards,

Aaron

Aaron-san,

Thank you for your help.

I posted the post by mistake...

The other post is saying that single-end output is possible, how do you think?

Hello Kuramochi-san,

My apologies. I may have misunderstood the actual question.

The Line outs are fully differential but they can be connected as if they are SE. For example, if you'd just like to use LEFT_LOP to connect and leave RIGHT_LOP floating, then that is fine.

Regards,

Aaron
