用分立元件搭的功放!可以达到的参数是:(1)在放大通道的正弦信号输入电压幅度为(5~700)mVpp,采用双电源供电,不大于±20V;等效负载电阻RL为8Ω下,放大器应满足:(功率放大部分单独供电) ① 最大不失真输出功率POR≥15W;(失真度小于5%) ② 带宽BW≥(40~20000)Hz;(功放部分) ③ 在POR下的效率≥50%; ④在前置放大级输入端交流短接到地时,RL=8Ω上的交流声VPP≤400mV。 ⑥具有音量调节功能。
When the MX27C512 is delivered, or it is erased, the chip has all 512K bits in the "ONE" or HIGH state. "ZEROs" are loaded into the MX27C512 through the procedure of programming. For programming, the data to be programmed is applied with 8 bits in p
