Hi cktlife,
Both offset and noise will degrade the converterīs resolution. However, usually offset errors are much larger than thermal noise induced errors due to resistor sizing, as Carl suggested. KT/C noise might eventually be important depending on the C involved and obviously the temperature the circuit works at. If T is large enough, the noise effect might be comparable to the offset contribution to the resolution degradation. I would say the total noise power (within the converterīs bandwidth, and including the offset power) must be less than 1LSB if look for a more comprenhensive definition.
