3FE
3FD
3FF
Indicates the ability of the A/D converter to discriminate analog variation
Expresses the deviation between actual conversion characteristics and a straight line connecting the device’s
zero transition point (00 0000 0000
1111 1111)
Expresses the deviation of the logical value of input voltage required to create a variation of 1 LSB in output
code.
