APPLICATION INFORMATION

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 temperature range is shown in Table 2, below. This

table is the reference from which the LM94021 accuracy specifications (listed in the ELECTRICAL

CHARACTERISTICS section) are determined. This table can be used, for example, in a host processor look-up

table.
