    Hi Prasad,

    I would like to ask you a couple questions about your application to narrow down the suggestions:
    How many channels do you want to mix?
    What is the input signal nature, digital or analog?

    Best regards,

    Hai Ivan,

    1. I need 6 channel mixer. First three channels used for dynamic mic and condenser mic ,remaining three channels used for line input's. Output channels required is two. 

    2. I need gain of about 60db for each channel.

    3. Input signal nature is analog.

    4.Low noise.

    Thanks & Regards,

    Prasad.

    Prasad,

    In analog-to-analog application I think that probably an opamp (or some of them) could be used for this. You could set an opamp in summing configuration to mix the signals into one analog output.
    In analog-to-digital application you should look into our audio ADCs. TLV320ADC3101 could be one option. For further assistance in audio ADCs and CODECs you can post into Audio Converter forum: e2e.ti.com/.../
