●Power Dissipation
Power dissipation (total loss) indicates the power that the IC can consume at Ta=25°C (normal temperature). As the IC
consumes power, it heats up, causing its temperature to be higher than the ambient temperature. The allowable
temperature that the IC can accept is limited. This depends on the circuit configuration, manufacturing process, and
consumable power.
Power dissipation is determined by the allowable temperature within the IC (maximum junction temperature) and the
thermal resistance of the package used (heat dissipation capability). Maximum junction temperature is typically equal to the
maximum storage temperature. The heat generated through the consumption of power by the IC radiates from the mold
resin or lead frame of the package. Thermal resistance, represented by the symbol θja°C/W, indicates this heat dissipation
capability. Similarly, the temperature of an IC inside its package can be estimated by thermal resistance.
Figure 24. (a) shows the model of the thermal resistance of the package. The equation below shows how to compute for the
Thermal resistance (θja), given the ambient temperature (Ta), maximum junction temperature (Tjmax), and power
dissipation (Pd).
θja = (Tjmax - Ta) / Pd
℃/W
・・・・・ (Ⅰ)
The Derating curve in Figure 24. (b) indicates the power that the IC can consume with reference to ambient temperature.
Power consumption of the IC begins to attenuate at certain temperatures. This gradient is determined by Thermal
resistance (θja), which depends on the chip size, power consumption, package, ambient temperature, package condition,
wind velocity, etc. This may also vary even when the same of package is used. Thermal reduction curve indicates a
reference value measured at a specified condition. Figure 25. (c) shows an example of the derating curve for
BA4558Yxxx-M.

●Operational Notes
1) Processing of unused circuit
+
-
It is recommended to apply connection (see the Figure 30.) and set the non
inverting input terminal at the potential within input common-mode voltage range
(Vicm), for any unused circuit.
Connect
to Vicm
Vicm
2) Input voltage
VEE
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.
Figure 30. The example of
application circuit for unused op-amp
VCC
protection
3) Maximum output voltage
resistor
+
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
VEE
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 Figure 31., thereby protecting
against load shorting.
5) Power supply (split supply / single supply) in used
Figure 31. The example of
output short protection
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 piezo
resistance effects.
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.
