there is such appnote in TIwebsite.
Usefull bits - on 4.5mV full scale
range signal i have at least 3000 "true" divisions. TI's appnote
reports better results that these 3000 (10'000).
On other hands -
this is slow aplication, with big averaging.

have any of you guys used SD16 ADC in your application, whats the
useful number of bits, i am in a fix whether to use an external serial
ADC like AD977 or an SD16 of 427, Ad977 has obviously more advantages.
but has some one made these comparisions?
