B A4510xxx Datasheet ●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. Figure 29. (a) 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 ℃/W ・・・・・ (Ⅰ) Derating curve in Figure 29. (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. Figure 30. (c) show a derating curve for an example of BA4510.

B A4510xxx Datasheet ●Operational Notes VCC 1) Processing of unused circuit It is recommended to apply connection (see the Figure 34.) and set the non + inverting input terminal at the potential within input common-mode voltage range Connect - (Vicm), for any unused circuit. to Vicm Vicm 2) Input voltage VEE 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 34. The example of application circuit for unused op-amp 3) Maximum output voltage Because the output voltage range becomes narrow as the output current VCC Increases, design the application with margin by considering changes in protection electrical characteristics and temperature characteristics. + resistor 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 Figure 35. thereby protecting against VEE load shorting. 5) Power supply (split supply / single supply) in used 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. Figure 35. The example of output short protection 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) Handing of IC 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. Status of this document The Japanese version of this document is formal specification.
