The offset voltage EOB is a potential difference between V
drops equivalent to 1/2 LSB of the voltage when the output data changes from “00000000” to “00000001”.
EOT is a potential difference between V
1/2LSB of the voltage when the output data changes from “11111111” to “11111110”.
Clamp offset voltage varies individually. When using with R, G, B 3 channels, color sliding may be
generated.
