relationship between INL/DNL and no. of bits

in some literatures, authors will state that "we improved INL to 9.5b". What is the relationship between these three specifications of ADC?
 

Hi neoflash,
INL basically means the non linearity of the ADC. Now when a authour states 9.5b INL this means the max INL error in the ADC is less than 1 lsb at 9.5bits!! Or in other words the transfer function of the ADC deviates from the ideal one by 1lsb at 9.5bits.
Say for eg you have an ADC with +/- 8lsb INL at say 14bits this implies that the INL is accurate upto 11bits. In your case if the ADC has +/-1.5lsb INL at 10bits then its INL is 9.5 bit accurate

hope this helps
