LOW VOLTAGE VERSION

18.5.4 A-D converter standard characteristics

The lower line of the graph indicate the absolute precision errors. These are expressed as the deviation

from the ideal value when the output code changes. For example, the change in output code from “0E16”

to “0F16” should occur at 36.25 mV, but the measured value is 0.3 mV. Accordingly, the measured point

of change is 36.25 + 0.3 = 36.55 mV.

The upper line of the graph indicate the input voltage width for which the output code is constant. For

example, the measured input voltage width for which the output code is “0F16” is 2.2 mV. Accordingly, the

differential non-linear error is 2.2 – 2.5 = –0.3 mV (–0.12 LSB).
