The error in the input voltage that causes the last code
transition of FFFE to FFFF (hex) for 16-bit or 3FFE to 3FFF
(hex) for 14-bit devices (in default offset binary mode) or
7FFE to 7FFF (hex) for 16-bit or 1FFE to 1FFF (hex) for 14-
bit devices (in two’s complement mode) from the ideal
input voltage of 32,766.5 x (10/4.096) x (V
16-bit or 8190.5 x (10/4.096) x (V
devices after correction for offset error.
