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.

Under the high temperature environment, consider the power dissipation of IC when selecting the output current.
When the terminal short circuits are continuously output, the output current is reduced to climb to the temperature inside IC.

●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. The temperature that
can be accepted by IC chip depends on circuit configuration, manufacturing process, and consumable 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 inside 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 consumption, 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.

Technical Note
●Cautions on use
1) Absolute maximum ratings
Absolute maximum ratings are the values which indicate the limits, within which the given voltage range can 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 between 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 temperature 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 electricity, 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.
