Hola, Jacky,

This measurement must be done on the TPA2011D1 output. I will move this thread to the Audio Amplifiers Forum. I will ask to my colleague to take a look of it.

Best regards,
Luis Fernando Rodríguez S.

Hola Jacky,

I have performed the measurements with the next conditions Vdd=5V, Av=2V/V and RL= 8Ω. I obtained with a Vin=0.5 Vpp, an output power of 12.54 mW and with a Vin=1Vpp, an output power of 50.09mW.

Please let me know your opinion, or if you have more questions.

Best regards
