4.0 DETAILED DESCRIPTION
The TC1047 and TC1047A have an output voltage that
varies linearly with temperature in degrees Celsius.
Figure 4-1 shows a plot of the output voltage versus
temperature for the TC1047 and TC1047A. The
temperature slope is fixed at 10 mV/°C and the output
voltage at 0°C is 500 mV.
