1 High Output Current, Rail-to-Rail Input/Output Dual CMOS Operational Amplifier NJU779 GENERAL DESCRIPTION The NJU779 is a Rail-to-Rail input and output dual CMOS operational amplifier that features high output current drive. This device is stable to capacitive load and can charge and discharge capacitance quickly by high output current up to ma. In addition, it is ideal for buffer amplifiers as the output stage can supply a respectable amount of current with minimal headroom from either rail.

3 NJU779 Application Notes Package Power, Power Dissipation and Output Power IC is heated by own operation and possibly gets damage when the junction power exceeds the acceptable value called Power Dissipation P D. The dependence of the NJU779 P D on ambient temperature is shown in Fig. The plots are depended on following two points. The first is P D on ambient temperature ºC, which is the maximum power dissipation. And the second is W, which means that the IC cannot radiate any more. The second point derives from the relation that maximum junction temperature Tj max is the same as storage temperature T stg. Fig. is drawn by connecting those points and by the definition that the P D lower than ºC is constant. Therefore, the P D is shown following formula as a function of the ambient temperature between those points. Dissipation Power P D Tj max Ta ja [W] ( Ta = ºC to Ta = ºC ) Where, θja is heat thermal resistance which depends on parameters such as package material, frame material and so on. Therefore, P D is different in each package. While, the actual measurement of dissipation power on NJU779 is obtained using following equation. (Actual Dissipation Power) = (Supply Voltage V DD ) X (Supply Current I DD ) (Output Power Po) The NJU779 should be operated in lower than P D of the actual dissipation power. To sustain the steady state operation, take account of the Dissipation Power and thermal design.
