TLV320AIC3254: the distortion of TLV320AIC3254 question

Part Number: TLV320AIC3254

Hi Ti team,

    We found that the distortion of TLV320AIC3254 was too large, up to 2%. The 1KHz signal was played, and the measured waveform was shown in the figure below. We have broken all the periphery of the analog output and eliminate PCB interference as far as possible. sch as attachment

Could you give us some advise for this?thanks !
