NOTES: 2. Analog input voltages greater than that applied to REF+ convert to all 1s (1111111111), while input voltages less than that applied to REF − convert to all 0s (0000000000). The total unadjusted error may increase as this differential voltage falls below 4.75 V. 3. Linearity error is the difference between the actual analog value at the transition between any two adjacent steps and its ideal value after zero-scale error and full-scale error have been removed. 4. Zero-scale error is the difference between the actual mid-step value and the nominal mid-step value at specified zero scale. Full-scale error is the difference between the actual mid-step value and the nominal mid-step value at specified full scale. 5. Total unadjusted error is the difference between the actual analog value at the transition between any two adjacent steps and its ideal value. It includes contributions from zero-scale error, full-scale error, and linearity error. |
