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 absoluted 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 then 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.

(*13) 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.

●Examples of circuit
○Voltage follower
Voltage gain is 0 [dB].
This circuit controls output voltage (Vout) equal
input voltage (Vin), and keeps Vout with stable
because of high input impedance and low output
impedance.
Vout is shown next formula.
Vout=Vin
VDD

VSS
○Inverting amplifier
R2
VDD
Vin
R1
Vout
R1//R2
For inverting amplifier, Vin is amplified by voltage
gain decided R1 and R2, and phase reversed
voltage is outputed.
Vout is shown next formula.
Vout=-(R2/R1)・Vin
Input impedance is R1.
VSS
○Non-inverting amplifier
R1
R2
VDD
For non-inverting amplifier, Vin is amplified by
voltage gain decided R1 and R2, and phase is
same with Vin.
Vout is shown next formula.
Vout=(1+R2/R1)・Vin
This circuit realizes high input impedance because
Input impedance is operational amplifier’s input
Vout Impedance.

Technical Note
●Description of electrical characteristics
Described here are the terms of electric characteristics used in this technical note. Items and symbols used are also shown.
Note that item name and symbol and their meaning may differ from those on another manufacture’s document or general document.
1. Absolute maximum ratings
Absolute maximum rating item indicates the condition which must not be exceeded. Application of voltage in excess of absolute
maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of dharacteristics.
1.1 Power supply voltage (VDD/VSS)
Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power supply
terminalwithout deterioration or destruction of characteristics of internal circuit.
1.2 Differential input voltage (Vid)
Indicates the maximum voltage that can be applied between non-inverting terminal and inverting terminal without
deterioration and destruction of characteristics of IC.
1.3 Input common-mode voltage range (Vicm)
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.
1.4 Power dissipation (Pd)
Indicates the power that can be consumed by specified mounted board at the ambient temperature 25℃(normal temperature).

●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.190 (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.190(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. Fig191(c)-(f) show a derating curve
for an example of BU7261/41family,BU7262/42family.,7461/7441family,7462/7442family.

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 itsinput terminal within input common mode
voltage VDD+0.3[V].
Then, regardless of power supply voltage,VSS-0.3[V] can be applied to inputterminals 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 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
