7. Output Voltage Temperature Coefficient ï§ï¦ ÎVOUT ï·ï¶
ï¨ ÎTa ⢠VOUT ï¸
The shaded area in Figure 10 is the range where VOUT varies in the operation temperature range when the output
voltage temperature coefficient is ±120 ppm/°C.
VOUT [V]
Example of S-1206B30 typ. product
+0.36 mV/°C
VOUT(E)*1

Ta [°C]
*1. VOUT(E) is the value of the output voltage measured at Ta = +25°C.
Figure 10
A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.
ÎVOUT
ÎTa
[mV/°C]*1 = VOUT(S) [V]*2 Ã
