CMOS TEMPERATURE SENSOR IC
S-58LM20A Series
„ Precautions
• Wire each pin of VDD, VSS and VOUT carefully in order to set them in low impedance when wiring an IC on a patterned
board.
• In this IC, if load capacitance of the VOUT pin is large, VOUT pin voltage may oscillate. 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 (C_L1) : 300 pF or less
