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 the non-inverting terminal and inverting terminal without
deterioration or destruction of characteristics. Input common-mode voltage range of the maximum ratings not assures
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 the IC when mounted on a specific board at ambient temperature 25°C (normal
temperature). As for the packaged product, Pd is determined by the temperature that can be permitted by the IC in the
package (maximum junction temperature) and the 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 to 0 V.
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 currents at
non-inverting and inverting terminals.
2.4 Input Common-mode Voltage Range (Vicm)
Indicates the input voltage range where IC operates normally.
2.5 Maximum Output Voltage (VOM)
Indicates the voltage range that the IC can output under specified load condition. It is typically divided into high-level
output voltage and low-level output voltage. High-level output voltage indicates the upper limit of output voltage.
Low-level output voltage indicates the lower limit.
2.6 Large Signal Voltage Gain (Av)
Indicates the amplification rate (gain) of the output voltage against the voltage difference between the non-inverting
and inverting terminals. It is normally the amplification rate (gain) with reference to DC voltage.
Av = (Output voltage fluctuation) / (Input offset fluctuation)

●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 28 (a) shows the model of the thermal resistance of a 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 °C/W
・・・・・ (Ⅰ)
The Derating curve in Figure 28 (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 29 (c) shows an example of the derating curve for LM4559.

●Operational Notes
1) Processing of unused circuit
It is recommended to apply the connection (see Figure 30.) and set the
non-inverting input terminal at a potential within the Input Common-mode
Voltage Range (Vicm) for any unused circuit.
2) Applied voltage to the input terminal
For normal circuit operation of voltage comparator, please input a voltage for
its input terminal within Input Common-mode Voltage Range (Vicm). Then,
regardless of power supply voltage, (VEE) – 0.3V can be applied to input
terminals without deterioration or destruction of its characteristics.

application circuit for unused op-amp
3) Operating power supply (split power supply/single power supply)
The voltage comparator operates if a certain level of voltage is applied
between VCC and VEE. 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
electrical characteristics of IC. As an example, reduction of current capability may happen. Take consideration of the
effective power dissipation and thermal design with a sufficient margin. Pd is referenced to the provided power dissipation
curve.
5) Short circuits between pins and incorrect mounting
When mounting the IC on a printed circuit board, take notice of the direction and position of the IC. If IC is mounted
erroneously, it may be damaged. Also, when a foreign object is inserted between outputs, between output and VCC
terminal, or between output and VEE terminal, it causes short circuit which may damage the IC.
6) Usage under strong electromagnetic field
Be careful when using the IC under strong electromagnetic field because it may malfunction.
7) Usage of IC
When pressure is applied to the IC through warp on the printed circuit board, the characteristics may fluctuate due to the
piezo effect. Be careful with the warp on the printed circuit board.
8) Testing IC on the application board
When testing IC on the application board, in cases where the capacitor is connected to low impedance, make sure to
discharge per process because there is a possibility that the IC may be damaged due to stress. When removing IC from
the application board, it is essential to cut the supply voltage. As a countermeasure against the static electricity, observe
proper grounding during fabrication process and take due care when carrying and storing it.
9) The IC destruction caused by capacitive load
The IC may be damaged when VCC terminal and VEE terminal is shorted with the charged output terminal capacitor.
When IC is used as an operational amplifier or as an application circuit where oscillation is not activated by an output
capacitor, output capacitor must be kept below 0.1μF in order to prevent the damage mentioned above.
10) Decoupling capacitor
Insert a decoupling capacitor between VCC and VEE for stable operation of operational amplifier.
