(b) Derating curve
●Power Dissipation
Power dissipation(total loss) indicates the power t hat can be consum ed by I C at Ta= 25℃(normal temper ature). IC is heat ed
when it consumed p ower, and the temperat ure of IC chip becom es higher than ambie nt 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, represent ed by the symbol θja℃/W.The t emperature of IC inside th e 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) in dicat es power that can be consumed by IC with referenc e t o ambient t emperat ure. Po wer t hat
can be consumed by IC with reference to ambient temperature. Power t hat 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 consumptio n, package, ambient t emperat ure, package conditi on, wind velocity, etc even when the same of
package is used. Thermal reduction curv e indicat es a r efer ence va lu e measure d at a sp ecified c on ditio n. F ig.51(c), (d) show

●Operational Notes
1) Processing of unused circuit
It is recommended to ap ply connect ion (see the F ig.55) and set t he non invertin g
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 in put terminal is possible without c ausing 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 charact erist ics.
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.
Th e r e f o re , t h e s i n g l e s u p p l y O p - A m p c a n be us e d f o r d o uble 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 t o 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 radiat ion-resistant.
10) IC Handling
When stress is applied to I C because of deflection or bend of board, the characteristics may fluctuate due to piezo electric
(piezo) effect.
11) Inspection on set board
During testing, turn on or off the power befor e mounting or dismounting the board f rom 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 elect ro static voltages during IC handling, transportation, and storage.
12) Output capacitor
When VCC terminal is shorted to VEE (GND) potential and an elect ric charge has accumulated on the external capacitor,
connected to output terminal, accumulated charge may be discharged VCC terminal via the parasitic element within the
ci rcuit or terminal prot ec t i on element. T h e element in the c i r c uit may be d amaged (thermal destruction). When usi ng 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 capaci tor connected to output terminal below 0.1μF in order to prevent damage to IC.

CLASSⅣ CLASSⅢ
2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which
a failure or malfunction of our Products may cause. The following are examples of safety measures:
[a] Installation of protection circuits or other protective devices to improve system safety
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure
3. Our Products are designed and manufactured for use under standard conditions and not under any special or
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any
special or extraordinary environments or conditions. If you intend to use our Products under any special or
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of
product performance, reliability, etc, prior to use, must be necessary:
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,
H2S, NH3, SO2, and NO2
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items
[f] Sealing or coating our Products with resin or other coating materials
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning
residue after soldering
[h] Use of the Products in places subject to dew condensation
4. The Products are not subject to radiation-proof design.
5. Please verify and confirm characteristics of the final or mounted products in using the Products.
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect
product performance and reliability.
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual
ambient temperature.
8. Confirm that operation temperature is within the specified range described in the product specification.
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in
this document.
Precaution for Mounting / Circuit board design
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product
performance and reliability.
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the
ROHM representative in advance.
For details, please refer to ROHM Mounting specification
