Part Number: TPA3136D2

Hello Audio Folks, a customer is asking for the IMD (intermodulation distortion) of TPA3136 at 1W output. Do we have a figure? Customer test it and get 0.29%. They are asking whether we can achieve 0.02%.

Hi, Kes

Could you check with customer what is the input frequency when they do the IMD test?My understand is there should be two tones at TPA3136D2 input, F1=??, F2=??.
