The shadowed area in Figure 11 is the range where VOUT varies in the operating temperature range

when the temperature coefficient of the output voltage is ±150 ppm/°C.

A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.

∆VOUT [mV / °C]*1 = [ VOUT(S) V]*2 × ∆VOUT [ppm / °C]*3 ÷1000
