Hi Jovialjha,
Below is the short list of Sigma delta ADC that possibly fit to your requirement.
ADI Sigma-Delta ADC portfolio range from 8bit to 24 bit resolution. And these parts are available with their evaluation board and software, you can visit ADI website Analog Devices | Mixed-signal and digital signal processing ICs for details. In case you wanted search other products base from your specification, you use parametric search .Please refer to link Selection Table for Precision below.
These ADCs are already packaged and access to the output quantizer might not be possible. There is the Dout, pin which outputs the conversion results.
