Kindly suggest me instrumentation amplifier ic wid quad or dual inputs to amplify micro volt signal to voltage and ADC with noise filters.
You could use the AD8222 for this. It has -140dB CMRR at maximum gain, and has 250nVpp 0.1 to 10Hz noise, which is the lowest we have for any of our duals. For optimal noise performance, it is best to use this in a dual supply configuration. That will also be best for you not to run into the input common mode limitations of the amplifier.
I will check back with you for the ADC.
