CMOS TEMPERATURE SENSOR IC
S-5813A/5814A Series
The S-5813A/5814A 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.

4. Line regulation (ΔVOUT1
)
ΔVOUT1 indicates the output voltage dependency of the input voltage. That is, the values express how the output voltage
changes, when input voltage is changed under the condition that output current is fixed.
5. Load regulation (ΔVOUT2
)
ΔVOUT2 indicates the output voltage dependency of the output current. That is, the values express how the output
voltage changes, when output current is changed under the condition that input voltage is fixed.

Precautions
• Wiring patterns for the VDD pin, VOUT pin, and VSS 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 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

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.
