CMOS TEMPERATURE SENSOR IC
S-58LM20A Series
Rev.1.2_00
In this IC, it is necessary to add a capacitor from an output pin to GND with a series resistor in the ambience having
excessive noise, as seen in Figure 12 and Figure 13. In the combination shown in Table 7, a time constant against heat
of this IC is much later than the time constant composed of RC, therefore it does not affect on the response time of this
IC.
