Power Dissipation  
Power dissipation(total loss) indicates the power that can be consumed by IC at TA=25°C(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 (°C/W).The temperature of IC inside the package can be estimated by  
this thermal resistance. Figure 11 shows the model of thermal resistance of the package. Thermal resistance θJA, ambient  
temperature TA, maximum junction temperature TJmax, and power dissipation PD can be calculated by the equation below:  
θJA = (TJmax - TA) / PD  
(°C/W)  
Derating curve in Figure 12 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.

Operational Notes  
1. Reverse Connection of Power Supply  
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when  
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power supply  
pins.  
2. Power Supply Lines  
Design the PCB layout pattern to provide low impedance supply lines. Separate the ground and supply lines of the  
digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting the analog  
block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of temperature and  
aging on the capacitance value when using electrolytic capacitors.  
3. Ground Voltage  
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.  
4. Ground Wiring Pattern  
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but  
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal  
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations  
on the ground voltage. The ground lines must be as short and thick as possible to reduce line impedance.  
5. Thermal Consideration  
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in  
deterioration of the properties of the chip. The absolute maximum rating of the PD stated in this specification is when  
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum rating,  
increase the board size and copper area to prevent exceeding the PD rating.  
6. Recommended Operating Conditions  
These conditions represent a range within which the expected characteristics of the IC can be approximately obtained.  
The electrical characteristics are guaranteed under the conditions of each parameter.  
7. Inrush Current  
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may flow  
instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power supply.  
Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring, and routing  
of connections.  
8. Operation Under Strong Electromagnetic Field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.

9. Testing on Application Boards  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may subject  
the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply should  
always be turned off completely before connecting or removing it from the test setup during the inspection process. To  
prevent damage from static discharge, ground the IC during assembly and use similar precautions during transport and  
storage.  
10. Inter-pin Short and Mounting Errors  
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in  
damaging the IC. Avoid nearby pins being shorted to each other especially to ground, power supply and output pin.  
Inter-pin shorts could be due to many reasons such as metal particles, water droplets (in very humid environment) and  
unintentional solder bridge deposited in between pins during assembly to name a few.  
11. Unused Input Pins  
Input terminals of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance  
and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small  
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and  
cause unexpected operation of the IC. So unless otherwise specified, unused input pins should be connected to the  
power supply or ground line.  
12. Regarding the Input Pin of the IC  
In the construction of this IC, P-N junctions are inevitably formed creating parasitic diodes or transistors. The operation  
of these parasitic elements can result in mutual interference among circuits, operational faults, or physical damage.  
Therefore, conditions which cause these parasitic elements to operate, such as applying a voltage to an input pin lower  
than the ground voltage should be avoided. Furthermore, do not apply a voltage to the input terminals when no power  
supply voltage is applied to the IC. Even if the power supply voltage is applied, make sure that the input pins have  
voltages within the values specified in the electrical characteristics of this IC.  
13. Ceramic Capacitor  
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with  
temperature and the decrease in nominal capacitance due to DC bias and others.
