by 3.5 V to ensure correct operation.
Total Unadjusted Error includes zero code error, relative accuracy and full-scale error.
Calculated after zero code error has been adjusted out.
Sample tested at 25

C to ensure compliance.
The glitch impulse transferred to the output of one converter (not adjusted) due to a change in the digital input code to another
addressed converter.
All input rise and fall times are measured from 10% to 90% of +5 V, t
