1.0 LM94022 Transfer Function
The LM94022 has four selectable gains, each of which can
be selected by the GS1 and GS0 input pins. The output volt-
age for each gain, across the complete operating temperature
range is shown in the LM94022 Transfer Table, below. This
table is the reference from which the LM94022 accuracy
specifications (listed in the Electrical Characteristics section)
are determined. This table can be used, for example, in a host
processor look-up table. A file containing this data is available
for download at www.national.com/appinfo/tempsensors.
