Figure 31. Typical Plot of Single Measurement Method After Calibrating for Offset and Gain At Two
Temperatures
The second mode uses a two-measurement (differential) method. This mode requires a second conversion with
a current 82 times larger. The voltage difference between the first (TEMP1) and second (TEMP2) conversion,
using 82 times the bias current, is represented by:
kT
q
ln(N)
where:
N is the current ratio = 82
k = Boltzmann’s constant (1.38054 1023 electrons volts/degrees Kelvin)
q = the electron charge (1.602189 1019 °C)
T = the temperature in degrees Kelvin
The equation for the relation between differential code and temperature may vary slightly from device to device
and can be calibrated at final system test by the user. This method provides resolution of approximately
1.5°C/LSB and accuracy of approximately ±4°C after calibrating at room temperature.
