DUAL OPERATIONAL AMPLIFIERS
LM358 is consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically to operate from a single power supply over a wide range of voltage. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. Application areas include transducer amplifier, DC gain blocks and all the conventional OP amp circuits which now can be easily implemented in single power supply systems.

求高手--LM358设计电压比较器：参数如下....
。检测USB接口D+两路比较器,D-的电压.，D-电压2.7V.。LM358工作电压5V。输出控制LED灯的亮灭。拜谢。电路越简单越好，D+电压2V
提问者采纳
网友才可以设计电路、灭 对应的 D+ 、D- 的状态你要说明 LED 亮
D+电压2V正负0.1V，D-电压2.7V正负0.1V，这两路都是固定的输出电压。当检测端低于这两个电压时LED灭，高于时LED亮。不知道这样叙述可不可以，多谢，
集成块管脚要标出来，资料里有。另一个电路只是改变取样电阻值，4.8K&与&5.2K&分压，输入&2.6&V基准电压。
您好按照这个电路做出实物，接上5V后LED等就亮了，D+,D-还没有接。怎么回事
没接这么行！你先用电阻分压代替 D 信号做实验，一样的结构，电压不同而已！有电位器最好，可以改变输入电压。
但是接上5V就亮了，正常吗？内部的两路运放只是反向输入端得到了一个1.95跟2.61的基准电压。同相输入端D+ D-都没输入，运放输入端有3V多的电压。应该不正常吧
正常，接5V时输入的10K电阻不能省略，不能直接接5V电源。
那我再试一下，麻烦能加我QQ嘛，我一电子公司技术员，希望以后能多多向你请教，
