13.7 How to Read A/D Converter Characteristics Table
438
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 an 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). %FSR is the ratio of a range of convertible analog input voltages expressed as a percentage,
and can be expressed as follows, independently of the resolution.
When 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 an actually measured value and a theoretical value.
It is a total of zero-scale error, full-scale error, linearity error, and a combination 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
