Description of electrical characteristics

Described here are the terms of electric characteristics used in this datasheet. 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

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)

2.10 Channel Separation (CS)

Indicates the fluctuation of input offset voltage or that of output voltage with reference to the change of output voltage

of driven channel.

2.11 Slew Rate (SR)

SR is a parameter that shows movement speed of operational amplifier. It indicates rate of variable output voltage

as unit time.

2.12 Transition Frequency (ft)

Indicates a frequency where the voltage gain of operational amplifier is 1.

●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.

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.

Fig. 55 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 Fig.56, thereby protecting against

load shorting.

5) Power supply (split supply / single supply) in used

Fig. 56 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 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.

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
