ADC conversion is
monotonic over full range.
0x7F to 0x80 transition specs
are excluded here.

Notes

12. SAR converters require a stable input voltage during the sampling period. If the voltage into the SAR8 changes by more than 1 LSB during the sampling period then

the accuracy specifications may not be met
