S-5815A

Rev.1.1_01 CMOS TEMPERATURE SENSOR IC S-5815A/5816A Series The S-5815A/5816A Series is a family of high-precision temperature sensor ICs on a single chip with a linear output voltage for temperature changes. Each chip is composed of a temperature sensor, a constant current circuit, and an operational amplifier. It can be used at temperatures ranging from –40°C to 100°C. These devices have much better linearity than other temperature sensors such as thermistors, and can be used for a wide range of temperature control applications.

Rev.1.1_01 • 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 pins. 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 (CL) : 2.2 µF or less VDD S-5815A/5816A Series VSS VOUT CL VOUT Figure 10 Caution The above connection diagram 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 resistor 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 exceeds 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. 10 Seiko Instruments Inc. Rev.1.1_01 Characteristics (Typical Data) 1.
