[7] Only allowed for a short time period.
[8] Minimum condition for VI = 4.5 V, maximum condition for VI = 5.5 V.
[9] The input threshold voltage of I2C-bus pins meets the I2C-bus specification, so an input voltage below 1.5 V will be recognized as a logic
0 while an input voltage above 3.0 V will be recognized as a logic 1.

VDDA = 2.5 V to 3.6 V; Ta = −40 °C to +85 °C unless otherwise specified. A/D converter frequency 4.5 MHz.

[1] Conditions: VSSA = 0 V, VDDA = 3.3 V.
[2] The A/D is monotonic, there are no missing codes.
[3] The differential non-linearity (ED) is the difference between the actual step width and the ideal step width. See Figure 6.
[4] The integral no-linearity (EL(adj)) is the peak difference between the center of the steps of the actual and the ideal transfer curve after
appropriate adjustment of gain and offset errors. See Figure 6.
[5] The offset error (EO) is the absolute difference between the straight line which fits the actual curve and the straight line which fits the
ideal curve. See Figure 6.
[6] The gain error (EG) is the relative difference in percent between the straight line fitting the actual transfer curve after removing offset
error, and the straight line which fits the ideal transfer curve. See Figure 6.
[7] The absolute voltage error (ET) is the maximum difference between the center of the steps of the actual transfer curve of the
non-calibrated A/D and the ideal transfer curve. See Figure 6.
