Accuracy
Built-in analog input
Accuracy of A/D conversion is determined by the accuracy for the full scale of digital output value.
The accuracy is within 0.5 % (20 digits) at ambient temperature of 255, within 1.0 % (40 digits) at ambient
temperature of 0 to 55, and within 1.5 % (60 digits) at ambient temperature of -20 to 0. (Except for the conditions under
the influence of noise)
