DESCRIPTION These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers . They operate from a single power supply over a wide range of voltages. 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. PIN CONNECTIONS (top view)

四运算放大器芯片LM124/LM224/LM324中文资料2010-01-30 11:41:29| 分类：电子元件资料 | 标签： |字号大中小订阅四运算放大器芯片LM124/LM224/LM324中文资料LM124/LM224/LM324是四运放集成电路，它采用14管脚双列直插塑料（陶瓷）封装，外形如图所示。

它的内部包含四组形式完全相同的运算放大器，除电源共用外，四组运放相互独立。

每一组运算放大器可用图1所示的符号来表示，它有5个引出脚，其中“+”、“-”为两个信号输入端，“V+”、“V-”为正、负电源端，“Vo”为输出端。

两个信号输入端中，Vi-（-）为反相输入端，表示运放输出端Vo的信号与该输入端的相位相反；Vi+（+）为同相输入端，表示运放输出端Vo的信号与该输入端的相位相同。

LM124/LM224/LM324的引脚排列见图2。

LM324, LM324A, LM324E, LM224, LM2902, LM2902E, LM2902V, NCV2902Single Supply Quad Operational AmplifiersThe LM324 series are low−cost, quad operational amplifiers with true differential inputs. They have several distinct advantages over standard operational amplifier types in single supply applications. Thequad amplifier can operate at supply voltages as low as 3.0 V or as high as 32 V with quiescent currents about one−fifth of those associated with the MC1741 (on a per amplifier basis). The common mode input range includes the negative supply, thereby eliminating the necessity for external biasing components in many applications. The output voltage range also includes the negative power supply voltage.

Representative Circuit Diagram(One−Fourth of Circuit Shown)Bias Circuitry Common to Four V CCV EE /GND+CIRCUIT DESCRIPTION The LM324 series is made using four internally compensated, two−stage operational amplifiers. The firststage of each consists of differential input devices Q20 andQ18 with input buffer transistors Q21 and Q17 and thedifferential to single ended converter Q3 and Q4. The firststage performs not only the first stage gain function but alsoperforms the level shifting and transconductance reductionfunctions. By reducing the transconductance, a smaller compensation capacitor (only 5.0 pF) can be employed, thussaving chip area. The transconductance reduction is accomplished by splitting the collectors of Q20 and Q18.Another feature of this input stage is that the input common mode range can include the negative supply or ground, in single supply operation, without saturating either the input devices or the differential to single−ended converter. The second stage consists of a standard current source load amplifier stage.Figure 2. Large Signal Voltage Follower Response1.V/DIVEach amplifier is biased from an internal−voltage regulator which has a low temperature coefficient thus giving each amplifier good temperature characteristics aswell as excellent power supply rejection.Split Supplies3.0 V to VCC(max)EE(max)Figure 3.706050403020101.010********LOAD CAPACITANCE (pF)Figure 4.

直流电机无级调整电路板的方法及原理图

直流电机无级调整电路板的方法及原理图时间：2010-04-21 23:14:51 来源：电子发烧友作者：直流电机无级调速电路板很贵，作者在维修一台包装机时得到一块直流电机调速板，经测绘并制作成功。

这块电路板电路简单，成本不高，制作容易.直流电机调速板电路及原理分析：220V交流电经变压器T降压，P2整流，V5稳压得到9V直流电压，为四运放集成芯片LM324(点击查看:四运算放大器芯片LM124/LM224/LM324中文资料)提供工作电源。

P1整流输出是提供直流电机励磁电源。

P4整流由可控硅控制得到0－200V的直流，接电机电枢，实现电机无级调速。

R1，C2是阻容元件，保护V1可控硅。

R3是串在电枢电路中作电流取样，当电机过载时，R3上电压增大，经D1整流，C3稳压，W1调节后进入LM324的12脚，与13脚比较从14脚输出到1脚，触发V7可控硅，D4 LED红色发光管亮，6脚电压拉高使V1可控硅不能触发，保护电机。

电机过载电流大小由W1调节。

市电过零检测，移相控制是由R5、R6降压，P3整流，经4N35隔离得到一个脉动直流进入14脚，从8脚到5脚输出是脉冲波，调节W2电位器即调节6脚的电压大小，可以改变脉冲的宽度，脉冲的中心与交流电过零时刻重合，使得双向可控硅很好地过零导通，D4是过载指示，D3是工作指示，W2是电机速度无级调节电位器。

图直流电机无级调速板电路图PCB电路板器件清单电路制作好后只要元件合格，不用调整就可使用。

我从100W－1000W电机都试过，运行可靠，调节方便，性能优良继电器是一种使用在较低的电压或较小电流的电路上，用来接通或切断较高电压、较大电流的电路的电气元件，也许可以这样说：用来控制较高电压或较大功率的电路的电动开关：给继电器工作线圈一个控制电流，继电器就吸合，对应的触点就接通或断开。

<br>在供电电路中，继电器也被称为接触器。

<br>从驱动继电器工作的电源要求（驱动线包工作电压）来分，一般继电器分交流继电器与直流继电器，分别用于交流电路和直流电路，另外，依据其工作电压的高低，有6、9、12、24、36、110、220、380等不同的工作电压，使用于不同的控制电路上。
