1.0 LM26LV V
Temperature Conversion Table
The LM26LV has one out of four possible factory-set gains,
Gain 1 through Gain 4, depending on the range of the Tem-
perature Trip Point. The V
in millivolts, at each discrete die temperature over the com-
plete operating temperature range, and for each of the four
Temperature Trip Point ranges, is shown in the Conversion
Table below. This table is the reference from which the
LM26LV accuracy specifications (listed in the Electrical Char-
acteristics section) are determined. This table can be used,
for example, in a host processor look-up table. See Section
1.1.1 for the parabolic equation used in the Conversion Table.
The V
Temperature, in °C, for each of the four gains corresponding
to each of the four Temperature Trip Point Ranges. Gain 1 is
the sensor gain used for Temperature Trip Point 0 - 69°C.
Likewise Gain 2 is for Trip Points 70 - 109 °C; Gain 3 for 110
- 129 °C; and Gain 4 for 130 - 150 °C. V
in bold font are for the Trip Point range.
