what will be the relationship between the ADC dymanic range and the receiver dynamic?

Will the ADC dynamic range be the bottom neck of the receiver dynamic range?


For example, I would like to design a receiver with (-90 dbm sensitivity and 5 dbm IIP3 with minimal SNR of 10), it will give a dynamic range of 2*(10+90-10)/3=60 dBm. Does this imply the ADC dynamic range needs to be 60dbm at least in order not to be the bottomneck?

Can anyone please kindly explain?

Thanks
