CMOS TEMPERATURE SENSOR IC
Rev.4.1_00
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.
The operating ambient temperature is 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.
Features
• Temperature accuracy
• Linear output voltage
• Nonlinearity
• Wide power supply voltage operation
• Low current consumption
• Built-in operational amplifier
• Output voltage referred to VSS
• Lead-free (Sn 100%), halogen-free
S-5813A Series : ±5.0°C (–30°C to +100°C)
S-5814A Series : ±2.5°C (–30°C to +100°C)
–11.04 mV/°C typ.
Ta = −30°C : 2.582 V typ.
Ta = +30°C : 1.940 V typ.
Ta = +100°C : 1.145 V typ.
±0.5% typ. (–20°C to +80°C)
VDD = 2.4 V to 10.0 V (+25°C)
4.0 μA typ. (+25°C)
Applications
• Compensation of high-frequency circuits such as cellular phones and radio equipment
• Compensation of oscillation frequency in crystal oscillator
• LCD contrast compensation
• Compensation of amplifier gain
• Compensation of auto focus circuits
• Temperature detection in battery management
• Overheating prevention for charged batteries or halogen lights
Package
• SNT-4A

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 (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.
