For the ADC, based from the data that you mentioned, I would recommend checking AD7903(16 bit- 2Channel SAR ADC), AD7175-2 and AD7176-2 (24 bit 250k, 4Channel Sigma Delta ADC). For future reference, you can try performing a parametric search in the ADI website and filter the parameters based from the needed specification from your application.
