    Hi, Vamsi,

    The headphone outputs can be used as the input to TPA3101D1. I suggest a simple RC filter before the TPA input to filter out high freq noise.

    reg,

    Paul.

    Can I use TPA3101d2 with an audio speaker whose rating is 4W on the input for continuous use which would be a 5.66V sine wave in practical usage if not please suggest some method of controlling the output of the audio for the above purpose like decreasing the gain etc
    Also I am using CODEC: PCM2912 and speaker I am using is CMS0401KL-1X (digkey code : 102-1305-ND)
