TPA2010D1: How to connect IN- for single ended application? and how to connect IN-/IN+ to which channel (left or right)

Hi Karl chang,

You can connect both channels to TPA2011D1, but the amplifier will be playing two signals together.
I understand the Codec output is stereo, so you could use a stereo audio amplifier like TPA2008D2 or TPA2026D2.

Hi sir

thanks your reply and suggestion. We just need to use Mono solution due to cost and layout consider.

Please help us check the schematic again if had any problem?

Hi Sir

 Do  you have any suggest for our AMP( TPA2010D1) design ?

Thanks~

Dear Sir

we'd to change to dual single ended design as below 

but we want to double confirm the CI1/CI2 and CP value. Must follow this value in 11.2.1.2 of spec.?

Hi,

You can use similar values, but you should follow the formulas of the TPA2011D1 Summing Two Single-Ended Inputs section.

There is no audio output for the schematic posted on April-15. so we switched to the schematic posted on May-8. May I know why April-15 schematic doesn't work? and could you make sure May-5 schematic would work normally? Thank you.

Hi Karlchang,

The schematic posted on April 15 should work fine, so Is the Codec delivering a differential input? If not, perhaps the Codec's signal is a single-ended input signal and this could be avoiding to get an output signal due to the differential input of the TPA2010D1.
If you are using a single-ended input signal could use the original schematic, but one Codec's output and one TPA2010D1's input should be tied to GND. You could select Line2-R and IN+.
