... These leakage currents cause an offset voltage to appear across any series source resis- tance on the selected channel. Therefore, any source resis- tance greater than 1 k (Motorola test condition) may induce errors in excess of guaranteed specifications. There are three tests available that verify the functionality of all the control logic as well as the successive approxima- tion comparator ...
