TEMP
VS DIE TEMPERATURE CONVERSION TABLE
The LM26LV/LM26LV-Q1 has one out of four possible factory-set gains, Gain 1 through Gain 4, depending on
the range of the Temperature Trip Point. The V
the range of the Temperature Trip Point. The V
TEMP
temperature sensor voltage, in millivolts, at each discrete die
temperature over the complete operating temperature range, and for each of the four Temperature Trip Point
ranges, is shown in the
ranges, is shown in the
. This table is the reference from which the LM26LV/LM26LV-Q1
accuracy specifications (listed in the
section) are determined. This table can be used,
for example, in a host processor look-up table. See
for the parabolic
equation used in the Conversion Table.

The V
TEMP
temperature sensor output voltage, in mV, vs Die 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
Points 70 - 109 °C; Gain 3 for 110 - 129 °C; and Gain 4 for 130 - 150 °C. V
DD
= 5.0V. The values in bold font are for the Trip Point
range.
