32-bit ARM Cortex-M3 microcontroller
[6] 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 28.
[7] 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 28.
[8] The absolute error (ET) is the maximum difference between the center of the steps of the actual transfer
curve of the non-calibrated ADC and the ideal transfer curve. See Figure 28.
[9] See Figure 29.
[10] 8-bit resolution is achieved by ignoring the lower four bits of the ADC conversion result.
