1. Output power test ：CS8683 Output power vs TPA3116 Almost unanimously . Output power test ： Testing conditions ：RL=4Ω
2. Harmonic distortion THD test ： Testing conditions ：RL=4Ω,Po=50W, PVCC=24V CS8683 In the middle and low frequency band THD Than TPA3116 Small . CS8683 At high frequencies THD Than TPA3116 Big .
3. Intermodulation distortion IMD test ( Test frequency point 100Hz contrast 8kHz,4：1 Amplitude ratio of )： Testing conditions ：RL=4Ω,PVCC=24V Before topping distortion ,CS8683 Intermodulation distortion IMD Than TPA3116 Small obvious .
