Notes
1.
As the programming range for the internally generated V
LCD
allows values above the maximum allowed V
LCD
, the
user has to ensure, while setting the V
OP
register and selecting the temperature compensation, that the V
LCD
limit of
maximum 9 V will never be exceeded under all conditions and including all tolerances.
LCD outputs are open circuit, inputs at V
DD
or V
