Appendix 10. M37906M4C-XXXFP standard characteristics
4. A-D converter standard characteristics
The lower lines 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 M37906M4C-XXXFP’s
output code from 159 to 160 should occur at 797.5 mV, but the measured value is +2.75 mV. Accordingly,
the measured point of change is 797.5 + 2.75 = 800.25 mV.
The upper lines 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 56 is 6.0 mV, so that the differential
non-linear error is 6.0 – 5 = 1.0 mV (0.20 LSB).
