It is recommended not to use an external capacitor between the VOUT and VSS pin. When using an external capacitor, set near the VOUT pin. When connecting an A/D converter etc. to the VOUT pin, the input pin capacitance of the A/D converter and the parasitic capacitance component between wires are included as load capacitance. To prevent oscillation, it is recommended to use the following output load condition. Load capacitance of VOUT pin (CL1) : 300 pF or less VDD S-58LM20A Series VSS VOUT CIN CL1 VOUT Figure 11 Caution The above connection diagram and constant will not guarantee successful operation. Perform through evaluation using the actual application to set the constant. Seiko Instruments Inc. 11 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.
