Accuracy Characteristics VTEMP Analog Temperature Sensor Output Accuracy

(1)

There are 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. These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in the

LM26LV/LM26LV-Q1 Conversion Table.

(1)

Changes in output due to self heating can be computed by multiplying the internal dissipation by the temperature resistance.

(2)

Limits are guaranteed to TI's AOQL (Average Outgoing Quality Level).

(3)

Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Conversion Table at the

specified conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the

specified conditions. Accuracy limits do not include load regulation; they assume no DC load.
