DETAILED DESCRIPTION
The NCT47 has an output voltage that varies linearly with
temperature in degrees Celsius. Figure 1 shows a plot of the
output voltage versus temperature for the NCT47. The
temperature slope is fixed at 10 mV/°C, and the output
voltage at 0°C is 500 mV.
VOUT = (10 mV/°C) (Temperature °C) + 500 mV
