S-8120C

Rev.4.3_00 CMOS TEMPERATURE SENSOR IC S-8110C/8120C Series The S-8110C/8120C 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.

It is recommended not to use the external capacitor between the VOUT and VSS pin. In case of using external capacitor, mount it near the VOUT pin. When connecting A/D converter etc. to the VOUT pin, input pin capacitance of 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) : 100 pF or less • In this IC, if load resistance of VOUT pin is small, VOUT pin voltage may oscillate. It is recommended not to use the external resistor between the VOUT and VSS pin. When connecting A/D converter etc. to the VOUT pin, input resistance of A/D converter and the parasitic resistance component between wires are included as load resistance. To prevent oscillation, it is recommended to use the following output load condition. Load resistance of VOUT pin (RL) : 500 kΩ or more VDD S-8110C/8120C VOUT Series VSS CL RL VOUT Figure 9 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 current 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. • In determining output current, attention should be paid to the output current value specified in the Table 5 to Table 6 for electrical characteristics and the footnote *1 of the Table 5 to Table 6. • SII claims no responsibility for any and all disputes arising out of or in connection with any infringement of the products including this IC upon patents owned by a third party. 10 Seiko Instruments Inc. Rev.4.3_00 CMOS TEMPERATURE SENSOR IC S-8110C/8120C Series Typical Characteristics Temperature (Ta) vs. Output voltage (VOUT) 2.2 2.0 1.8 VOUT [V] 1.6 1.4 1.2 1.0 0.8 -40 -20 0 20 40 Ta [°C] 60 80 100 Temperature (Ta) vs. Current consumption (IDD) 10 9 8 VDD = 10.0 V 7 6 5 VDD = 5.0 V 4 VDD = 2.4 V 3 2 1 0 -40 -20 0 20 40 Ta [°C] IDD [μA] 60 80 100 Error range of each temperature The difference of the temperature, which is converted with the approximated straight line and actual temperature [°C] 6 4 2 0 -2 -4 -6 -40 -20 0 20 40 Ta [°C] 60 80 Approximated straight line: VOUT [mV] = -8.2 [mV] × Ta [°C] + 1705 [mV] Power supply voltage (VDD) vs. Current consumption (IDD) 10 Ta = -40 °C 9 8 7 6 Ta = 30 °C 5 4 Ta = 100 °C 3 2 1 0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 10.0 100 VDD [V] IDD [μA] Power supply voltage (VDD) vs. Output voltage (VOUT) 2.038 2.037 2.036 2.035 2.034 2.033 2.032 2.031 2.030 2.0 Ta = -40 °C 1.479 1.478 1.477 1.476 1.475 1.474 1.473 1.472 1.471 2.0 Ta = 30 °C VOUT [V] 3.0 4.0 5.0 6.0 7.0 VDD [V] 8.0 9.0 10.0 VOUT [V] 3.0 4.0 5.0 6.0 7.0 VDD [V] 8.0 9.0 10.0 0.887 0.886 0.885 0.884 0.883 0.882 0.881 0.880 0.879 2.0 Ta = 100 °C VOUT [V] 3.0 4.0 5.0 6.0 7.0 VDD [V] 8.0 9.0 10.0 Seiko Instruments Inc. 11 CMOS TEMPERATURE SENSOR IC S-8110C/8120C Series Rev.4.3_00 Load current (IOUT) vs. Output voltage (VOUT) 2.5 Ta = -40 °C 2.0 VOUT [V] 1.5 1.0 0.5 0 0 Ta = 100 °C VOUT [V] Ta = 30 °C 2.0 1.5 1.0 0.5 0 0 Ta = 100 °C Ta = 30 °C VDD = 2.4 V 2.5 Ta = -40 °C VDD = 5.0 V 2.5 2.0 VOUT [V] 1.5 1.0 0.5 0 0 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 IOUT [mA] VDD = 10.0 V 0.5 1.0 1.5 2.0 2.5 3.0 3.5 4.0 4.5 5.0 IOUT [mA] Ta = -40 °C Ta = 30 °C Ta = 100 °C 2.0 4.0 6.0 8.0 IOUT [mA] 10.0 12.0 14.0 Heat response Time (t) vs. Output voltage (VOUT) When packages are put into the air of 100 degrees from the air of 25 degrees 1.6 1.5 1.4 1.3 1.2 1.1 1.0 0.9 0.8 When packages are put into the liquid of 100 degrees from the air of 25 degrees 1.6 1.5 1.4 1.3 1.2 1.1 1.0 0.9 0.8 SNT-4A SC-82AB VOUT [V] SNT-4A SC-82AB 0 30 60 90 t [s] 120 150 180 VOUT [V] 0 10 20 30 t [s] 40 50 60 Start up response Ta = 25 °C, CL = 100 pF, RL = 10 MΩ Ta = 25 °C, CL = 100 pF, RL = 10 MΩ VDD (= 6.0 V) 1 V / div.
