Hi,

Could you please tell us how to evaluate using pure resistor load?
We found that there is a reference of schematic diagram on page 4 of TPA2011D1 evm user's guide.
Can we refer to this?
In addition, if you have an application note for this issue, could you please send it to us?

Best Regards,
Kato

You can hook up an 8 Ohm resistor (2W) to the speaker terminals and evaluate by measuring the signal over this resistor (e.g. with an AP). Make sure that you use a 30kHz cut-off LP filter (simple RC) to avoid out of band noise problems.
