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.
