Here, special terms unique to the A/D converter are explained.
(1) Resolution
(2) Overall error
This is the minimum analog input voltage that can be identified. That is, the percentage of the analog input
voltage per bit of digital output is called 1 LSB (Least Significant Bit). The percentage of 1 LSB with respect to
the full scale is expressed by %FSR (Full Scale Range). %FSR indicates the ratio of analog input voltage that
can be converted as a percentage, and is always represented by the following formula regardless of the
resolution.
1 LSB is as follows when the resolution is 12 bits.
1 LSB = 1/2
Accuracy has no relation to resolution, but is determined by overall error.
This shows the maximum error value between the actual measured value and the theoretical value.
Zero-scale error, full-scale error, linearity error and errors that are combinations of these express the overall
error.
Note that the quantization error is not included in the overall error in the characteristics table.
