CMOS TEMPERATURE SENSOR IC Rev.4.1_00 S-5813A/5814A Series Seiko Instruments Inc. 11  Precautions

• Wiring patterns for the VDD pin, VSS pin, and VOUT pin should be designed to hold low impedance.
• In this IC, if load capacitance of the VOUT pin is large, VOUT pin voltage may oscillate. It is recommended not to use the external capacitor between the VOUT and VSS pin. When using an external capacitor, mount it 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 L) : 2.2 μF or less VOUTVDD VSS CL VOUT S-5813A/5814A Series CIN Figure 8 Caution The above connection diag ram and constant will not guarantee successful operation. Perform through evaluation using the actual application to set the constant.
• Please do not connect a pull-up resi stor to the output voltage pin.
• The application condition for input voltage, output voltage and load voltage must not exceed the package power dissipation.
• Do not apply an electrostatic discharge to this IC that ex ceeds the performance ratings of the built-in electrostatic protection circuit.
• SII claims no responsibility for any disputes arising out of or in connection with any infringement by products including this IC of patents owned by a third party.
