TERMINOLOGY
Integral Nonlinearity
The maximum deviation from a straight line passing through
the endpoints of the ADC transfer function. The endpoints of
the transfer function are zero scale (a point 1 LSB below the
first code transition), and full scale (a point 1 LSB above the last
code transition).
Rev. A | Page 9 of 44
Differential Nonlinearity
The difference between the measured and the ideal 1 LSB
change between any two adjacent codes in the ADC.
Offset Error
The deviation of the first code transition (00…000) to
(00…001) from the ideal (AGND + 1 LSB).
Gain Error
The deviation of the last code transition (111…110) to
(111…111) from the ideal (V
REF
1 LSB) after the offset error
has been adjusted out.
On Resistance
A measure of the ohmic resistance between the drain and the
source of the switch drivers.
