absolute maximum rating or use out of absolute maximum rated temperature environment may cause deterioration of
characteristics.
1.1 Power supply voltage (VCC-VEE)
Indicates the maximum voltage that can be applied between the positive power supply terminal and negative power
supply terminal without 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 normal operation 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).
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.
2. Electrical characteristics item
2.1 Input offset voltage (Vio)
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 0V.
2.2 Input offset current (Iio)
Indicates the difference of input bias current between non-inverting terminal and inverting terminal.
2.3 Input bias current (Ib)
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.
2.4 Input common-mode voltage range (Vicm)
Indicates the input voltage range where IC operates normally.
2.5 Large signal voltage gain (AV)
Indicates the amplifying rate (gain) of output voltage against the voltage difference between non-inverting terminal
and Inverting terminal. It is normally the amplifying rate (gain) with reference to DC voltage.
Av = (Output voltage fluctuation) / (Input offset fluctuation)
2.6 Circuit current (ICC)
Indicates the IC current that flows under specified conditions and no-load steady status.
2.7 Output saturation voltage (VOM)
Signifies the voltage range that can be output under specific output conditions.
2.8 Common-mode rejection ratio (CMRR)
Indicates the ratio of fluctuation of input offset voltage when in-phase input voltage is changed. It is normally the
fluctuation of DC.
CMRR = (Change of Input common-mode voltage)/(Input offset fluctuation)
2.9 Power supply rejection ratio (PSRR)
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)

Datasheet
●Power Dissipation
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 chip 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 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 θja℃/W.The temperature of IC inside the package can be estimated by this
thermal resistance. Fig.50(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 = (Tjmax-Ta) / Pd
℃/W
・・・・・ (Ⅰ)
Derating curve in Fig.50 (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 specified condition. Fig.51(c),(d) show
a derating curve for an example of BA4558, BA4558R.

●Operational Notes
1) Processing of unused circuit
It is recommended to apply connection (see the Fig.55) and set the non inverting
input terminal at the potential within input common-mode voltage range (Vicm),
for any unused circuit.
2) Input voltage
Applying (VEE - 0.3) to (VEE + 36)V
(BA4558R) to the input terminal is possible without causing deterioration of the
electrical characteristics or destruction, irrespective of the supply voltage.
However, this does not ensure normal circuit operation. Please note that the
circuit operates normally only when the input voltage is within the common mode
input voltage range of the electric characteristics.
3) Maximum output voltage
Because the output voltage range becomes narrow as the output current
Increases, design the application with margin by considering changes in
electrical characteristics and temperature characteristics.
4) Short-circuit of output terminal
When output terminal and VCC or VEE terminal are shorted, excessive Output
current may flow under some conditions, and heating may destroy IC. It is
necessary to connect a resistor as shown in Fig.56, thereby protecting against
load shorting.
5) Power supply (split supply / single supply) in used
Op-amp operates when specified voltage is applied between VCC and VEE.
Therefore, the single supply Op-Amp can be used for double supply Op-Amp as well.

6) Power dissipation (Pd)
Use a thermal design that allows for a sufficient margin in light of the power dissipation (Pd) in actual operating
conditions.
7) Short-circuit between pins and wrong mounting
Pay attention to the assembly direction of the ICs. Wrong mounting direction or shorts between terminals, GND, or other
components on the circuits, can damage the IC.
8) Use in strong electromagnetic field
Using the ICs in strong electromagnetic field can cause operation malfunction.
9) Radiation
This IC is not designed to be radiation-resistant.
10) IC Handling
When stress is applied to IC because of deflection or bend of board, the characteristics may fluctuate due to piezoelectric
(piezo) effect.
11) Inspection on set board
During testing, turn on or off the power before mounting or dismounting the board from the test Jig. Do not power up the
board without waiting for the output capacitors to discharge. The capacitors in the low output impedance terminal can
stress the device. Pay attention to the electro static voltages during IC handling, transportation, and storage.
12) Output capacitor
When VCC terminal is shorted to VEE (GND) potential and an electric charge has accumulated on the external capacitor,
connected to output terminal, accumulated charge may be discharged VCC terminal via the parasitic element within the
circuit or terminal protection element. The element in the circuit may be damaged (thermal destruction). When using this IC
for an application circuit where there is oscillation, output capacitor load does not occur, as when using this IC as a
voltage comparator. Set the capacitor connected to output terminal below 0.1μF in order to prevent damage to IC.
