A/D CONVERTER CHARACTERISTICS (See pg. 4 for Standard Conditions)
Notes: 1.
“LSB” is defined as V(VRef)/255, “Full Scale” is defined as V(VRef).
2.
OffsetADC: For an ideal converter, the first transition of its transfer curve occurs at
above zero. Offset error is the
amount of deviation between the measured first transition point and the ideal point.
FSErrorADC: For an ideal converter, the last transition of its transfer curve occurs at
. Full Scale Error is the
amount of deviation between the measured last transition point and the ideal point,
after subtracting the Offset from the measured curve.
DNLADC: DNL is defined as the difference between the ideal and the measured code transitions for successive A/D code outputs
expressed in LSBs. The measured transfer curve is adjusted for Offset and Fullscale errors before calculating DNL.
INLADC: The deviation of the measured transfer function of an A/D converter from the ideal transfer function. The INL error is also
defined as the sum of the DNL errors starting from code 00h to the code where the INL measurement is desired. The measured trans-
fer curve is adjusted for Offset and Fullscale errors before calculating INL.
