用TDA2822M功放块BTL应用电路能否代换8002B
除了外观其它都不一样
很便宜的,几毛钱一个,
具体的你可以找矽源特科技索要资料和样品
可以代换,试过
陈老师在永城哪里,想当面请教
看datasheet和典型应用电路图,LM4871与8002B非常相似,主要区别是第1脚
8002B
The device enters in shutdown mode when a high level is applied on this pin 当该引脚施加高电平时,器件进入关断模式
LM4871
Inverting input resistance that sets the closed-loop gain in conjunction with Rf. This resistor also forms a high pass filter with Ci at fC= 1/(2π RiCi).
反相输入电阻,用于设置闭环增益和Rf。 该电阻器还与Ci一起形成高通滤波器在fC = 1 /(2πRiCi)。
