1.0 LM94023 Transfer Function
The LM94023 has two selectable gains, selected by the Gain
Select (GS) input pin. The output voltage for each gain, across
the complete operating temperature range is shown in the
LM94023 Transfer Table, below. This table is the reference
from which the LM94023 accuracy specifications (listed in the
Electrical Characteristics section) are determined. This table
can be used, for example, in a host processor look-up table.
