ADC test conditions: V
DD
= 2.7 V, V
ref(A)
= 2.7 V, CLK = 20 MHz, FCLK2 = 2 MHz.
This resistor is switched off during Power-down mode and when the ADC is switched off (EADC = 0).
Parameter not measured in production, only verified on sampling basis.
See Fig.17 for specific FCLK2 range as function of V
DD
.
Absolute voltage error: the maximum difference between actual and ideal code transitions. Absolute voltage error
accounts for all deviations of an actual converter from an ideal converter.
Offset error: the difference between the actual and ideal input voltage corresponding to the first actual code transition.
Integral non-linearity: the maximum deviation between the edges of the steps of the transfer curve and the edges of
the steps of the ideal curve. The ideal step curve follows the line of least squares.
Differential non-linearity: the maximum deviation of the actual code width from the average code width.
Channel-to-channel matching: The difference between corresponding code transitions of actual characteristics taken
from different channels under the same temperature, voltage and frequency conditions.
