nded, LM4880 into the amplifying state port allocated through headphones tMOS gate of contacts and R, grounding, MOS tube off, feet to high power level, I. M4880 automatically shut down. l Y a LM4880 can also be made automatic application switching power amplifier circuit, as shown in Figure 5-42. LM4861 voltage at Sv can output 0.5w power, playback speaker inscribed machine outlet into the headset, O feet connected to the positive supply by Rv, current speaker automatically turns off. As you pull, LM4861 of O feet through contact and care, grounded into working condition, while I.M4880 but just off t work alternately with each other.
