High Quality Audio Dual Operational Amplifier NJM88 GENERAL DESCRIPTION The NJM88 is a high quality audio dual operational Amplifier with bipolar technology, strikes a balance between MUSES technology and mass-production technique. The original process tuning and the assembly technology, based on MUSES technology, make excellent sound and absorbing cost increases. The characteristics like Low noise (.nv/ Hz), Wide Bandwidth (MHz) and low distortion (.%) suitable for audio preamplifiers, active filters, and line amplifiers. NJM88 packages are EMP8 and small SSOP8 with copper frame.

NJM88 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 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. The second is W, which means that the IC cannot radiate any more. Conforming the maximum junction temperature Tjmax to the storage temperature Tstg derives this point. Fig. is drawn by connecting those points and conforming the P D lower than ºC to it on ºC. The P D is shown following formula as a function of the ambient temperature between those points. Dissipation Power P D = Tjmax - Ta θja [W] ( 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 IC is obtained using following equation. (Actual Dissipation Power) = (Supply Voltage V DD ) X (Supply Current I DD ) (Output Power Po) This IC 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. 8 7 Pd (mw) 6 EMP8 SSOP8-6 8 Ta ( C) Fig. Power Dissipations vs. Ambient Temperature Ver.--7 - -
