● Description
BU7261 G
High speed
Low pow er
Single
Dual
CMOS op-amp BU7261/BU7241 family and
BU7262/BU7242 family are input and output
full swing op-amp. These ICs integrate one
op-amp or two independent op-amps and phase
compensation capacitor on a single chip.
The features of these ICs are low operating supply
Voltage +1.8V to +5.5V(single supply) and low
supply current, extremely low input bias current.

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 VEE.

● 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.6 (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.6 (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. Fig7(c)-(f) show a derating curve for an example of BU7261series, BU7262series, BU7241,BU7242series.

● 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 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 deculing capacitance between VDD and VSS, for stable operation of operational amplifier.
11) Latch up
Be careful of input vltage that exceed the VDD and VSS. When CMOS device have sometimes occur
latch up operation. And protect the IC from abnormaly noise
