1.0 LM94021 Transfer Function
The LM94021 has four selectable gains, each of which can
be selected by the GS1 and GS0 input pins. The output
voltage for each gain, across the complete operating tem-
perature range is shown in the LM94021 Transfer Table,
below. This table is the reference from which the LM94021
accuracy specifications (listed in the Electrical Characteris-
tics 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.
