LM26LV/LM26LV-Q1 VTEMP 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 VTEMP 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 Conversion Table. This table is the reference from which the LM26LV/LM26LV-Q1

accuracy specifications (listed in the Electrical Characteristics section) are determined. This table can be used,

for example, in a host processor look-up table. See The Second-Order Equation (Parabolic) for the parabolic

equation used in the Conversion Table.

The VTEMP 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. VDD = 5.0V. The values in bold font are for the Trip Point

range.
