NOTES: (1) Adjustable to zero. Tested and guaranteed for 0 to +10V and
±
10V ranges only. (2) Peak-to-peak based on 99.9% of all codes. (3) FSR means full-
scale range and depends on the input range selected. (4) ADC conversion time is defined as the time that the Sample/Hold must remain in the Hold mode; i.e.,
the duration of the Sample/Hold command. This time must be added to the Sample/Hold acqusition time to obtain the total system throughput time. (5) Given for
reference only — this time overlaps with the ADC701 conversion time and does not affect system throughput rate.
