3.0 DETAILED DESCRIPTION
The TC1047 and TC1047A have an output voltage that
varies linearly with temperature in degrees Celsius.
Figure 3-1 shows a plot of the output voltage versus
temperature for the TC1047 and TC1047A. The
temperature slope is fixed at 10mV/°C, and the output
voltage at 0°C is 500mV.
