Note: Absolute maximum rating item indicates the condition which must not be exceeded. Application of voltage in excess of absolute maximum rating or use out absolute maximum rated temperature environment may cause deterioration of characteristics. (*1) The voltage difference between inverting input and non-inverting input is the differential input voltage. Then input terminal voltage is set to more than VSS.

Technical Note
Derating curve Power dissipation (total loss) indicates the power that can be consumed by IC at Ta=25(normal temperature). IC is heated when it consumed power, and the temperature of IC ship becomes higher than ambient temperature. T he temperature that can be accepted by IC chip depends on circuit configuration, manufacturing process, and co nsumable power is limited. Power dissipation is determined by the temperature allowed in IC chip (maximum junction temperature) and thermal resistance of package (heat dissipation capability).The maximum junction temperature is typically equal to the maximum value in the storage package (heat dissipation capability).The maximum junction temperature is typically equal to the maximum value in the storage temperature range. Heat generated by consumed power of IC radiates from the mold resin or lead frame of the package. The parameter which indicates this heat dissipation capability (hardness of heat release) is called thermal resistance, represented by the symbol θj-a[/W]. The temperature of IC insid e the package can be estimated by this thermal resistance. Fig.195 (a) shows the model of thermal resistance of the package. Thermal resistance θja, ambient temperature Ta, junction temperature Tj, and power dissipation Pd can be calculated by the equation below: θja = (Tj-Ta) / Pd [/W] ・・・・・ (Ⅰ) Derating curve in Fig.195(b) indicates power that can be consumed by IC with reference to ambient temperature. Power that can be consumed by IC begins to attenuate at certain ambient temperature. This gradient iis determined by thermal resistance θja. Thermal resistance θja depends on chip size, power consumptio n, package, ambient temperature, package condition, wind velocity, etc even when the same of package is used. Thermal reduction curve indicates a reference value measured at a specified condition. Fig196 (c)-(h) show a derating curve for an example Ground Sense Low Voltage Operation CMOS Operational Amplifiers series.

Cautions on use
1) Absolute maximum ratings Absolute maximum ratings are the values which indicate the limits, within which the given voltage range ca n be safely charged to the terminal. However, it does not guarantee the circuit operation.
2) Applied voltage to the input terminal For normal circuit operation of voltage comparator, please input voltage for its input terminal within input common mode voltage VDD + 0.3[V]. Then, regardless of power supply voltage, VSS-0.3[V] can be applied to input terminals without deterioration or destruction of its characteristics.
3) Operating power supply (split power supply/single power supply) The voltage comparator operates if a given level of voltage is applied bet ween VDD and VSS. Therefore, the operational amplifier can be operated under single power supply or split power supply.
4) Power dissipation (pd) If the IC is used under excessive power dissipation. An increase in the chip temperatur e will cause deterioration of the radical characteristics of IC. For example, reduction of current capability. Take consideration of the effective power dissipation and thermal design with a sufficient margin. Pd is reference to the provided power dissipation curve.
5) Short circuits between pins and incorrect mounting Short circuits between pins and incorrect mounting when mounting the IC on a printed circuits board, take notice of the direction and positioning of the IC. If IC is mounted erroneously, It may be damaged. Also, when a foreign object is inserted between output, between output and VDD terminal and VSS terminal which causes short circuit, the IC may be damaged.
6) Using under strong electromagnetic field Be careful when using the IC under strong electromagnetic field because it may malfunction.
7) Usage of IC When stress is applied to the IC through warp of the printed circuit board, The characteristics may fluctuate due to the piezo effect. Be careful of the warp of the printed circuit board.
8) Testing IC on the set board When testing IC on the set board, in cases where the capacitor is connected to the low impedance, make sure to discharge per fabrication because there is a possibility that IC may be damaged by stress. When removing IC from the set board, it is essential to cut supply voltage. As a countermeasure against the static electricit y, observe proper grounding during fabrication process and take due care when carrying and storage it.
9) The IC destruction caused by capacitive load The transistors in circuits may be damaged when VDD terminal and VSS terminal is shorted with the charged output terminal capacitor.When IC is used as a operational amplifier or as an application circuit, where oscillation is not activated by an output capacitor, the output capacitor must be kept below 0.1[μF] in order to prevent the damage mentioned above.
10) Latch up Be careful of input voltage that exceed the VDD and VSS. When CMOS device have sometimes occur latch up operation. And protect the IC from abnormaly noise
11) Decupling capacitor Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier.
