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.

Indicates the maximum voltage that can be applied between the positive po wer supply terminal and negative po wer
supply terminalwithout deterioration or destruction of characteristics of internal circuit.
Indicates the maximum voltage that can be applied between non-inverting terminal and inverting ter minal without
deterioration and destruction of characteristics of IC.
Indicates the maximum voltage that can be applied to non-inverting terminal and inverting terminal without
deterioration or destruction of characteristics. Input common-mode voltage range of the maximum ratings not assure
normal operation of IC. When normalOperation of IC is desired, the input common-mode voltage of characteristics
item must be followed.
Indicates the power that can be consumed by specified mounted board at the ambient temperature 25℃(normal
temperature).
As for package product, Pd is determined by the temperature that can be permitted by IC chip in the package
(maximum junction temperature) and thermal resistance of the package.
Indicates the voltage difference between non-inverting terminal and inverting terminal. It can be translated into the
input voltage difference required for setting the output voltage at 0 [V].
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
Indicates the current that flows into or out of the input terminal. It is defined by the average of input bias current at
non-inverting terminal and input bias current at inverting terminal.
Indicates the IC current that flows under specified conditions and no-load steady status.
Indicates the voltage range that can be output by the IC und er specified load condition. It is typically divided into
high-level output voltage and low-level output voltage. High-level output voltage indicates the upper limit of output
voltage. Low-level output voltage indicates the lower limit.
Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inve rting terminal
and inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage.
Av = (Output voltage fluctuation) / (Input offset fluctuation)
Indicates the input voltage range where IC operates normally.
Indicates the ratio of fluctuation of input offset voltage when in-phase input voltage is changed. It is normall y the
fluctuation of DC.
CMRR =(Change of Input common-mode voltage)/(Input offset fluctuation)
Indicates the ratio of fluctuation of input offset voltage when supply voltage is changed. It is normally the fluctuation of DC.
PSRR=(Change of power supply voltage)/(Input offset fluctuation)

Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage
of driven channel.
Indicates a noise voltage generated inside the operational amplifier equivalent by ideal voltage source connected in
series with input terminal.

●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 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 the rmal
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 with reference to ambient temperature. Power that can be consumed by IC begins to attenuate at
certain ambient temperature. This gradient is 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 specifi ed condition. Fig196(c) ~ (h)
show a derating curve for an example of low voltage full swing
CMOS Op-Amp.

●Notes for 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 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 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, bet ween output
and VDD terminal or 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) Decupling capacitor
Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier.
11) 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
12) Decupling capacitor
Insert the decupling capacitance between VDD and VSS, for stable operation of operational amplifier.
