11.6 How to Read A/D Converter Characteristics Table

This section describes the terms related to the A/D converter.
(1) Resolution
(2) Overall error
The minimum analog input voltage that can be recognized, i.e., the ratio of the analog input voltage to 1 bit of
digital output, is called 1 LSB (least significant bit). The ratio of 1 LSB to the full scale is expressed as %FSR
(full-scale range).
percentage, and can be expressed as follows, independently of the resolution.
Where the resolution is 10 bits, 1 LSB is as follows:
The accuracy is determined by the overall error, independently of the resolution.
This is the maximum value of the difference between the actually measured value and the theoretical value.
It is the total of the zero-scale error, full-scale error, linearity error, and combinations of these errors.
The overall error in the characteristics table does not include the quantization error.
1%FSR = (Maximum value of convertible analog input voltage – Minimum value of convertible analog
input voltage)/100
