LF353运放构成振荡电路
LF353运放构成振荡电路振荡电路如图1所示．由带通滤波器和反相放大器组成。
由R2、C2、R1、C1组成的带通滤波器构成放大器的正反馈电路。
当设定R1=R2=R．C1=C2=C时．在频率为fo时带通滤波器的相位为零。
因此．当把运算放大器的反馈电阻R3和R4设定为R3=2R4时．同相放大器的增益为3倍，在fo处的环路增益正好为1倍，电路产生振荡，并正好能维持振荡。
振荡频率可用fo=1／2πRC进行计算．方法如下：1.给定振荡频率fo和电阻R的值，计算电容器C的值。
例如设fo=1000Hz，R=10kΩ，则可以求得C=0.0159μF。
2．给定振荡频率fo和电容C的值，计算电阻R的值。
由于0.0159μF不是电容器的标称值．必须用几个电容器经串并联组合后才能实现，在制作电路时不但成本高，操作起来也很麻烦。
因此可以先确定电容量，再求电阻阻值。
例如此时将电容量设定为C=0.0159μF，即R=1／2πfoC=10.6kΩ。
对于该振荡电路来说即使环路增益只比1倍稍稍小一点点，电路也不会振荡。
所以在设计实际的电路时为了能确保振荡．将R3和R4设定为R3=2.2 R4的关系。
此时可以确保振荡．但又带来振荡会随时间不断增加，最后导致波形顶部被限幅的问题。
为此需在反馈电路中接入稳压二极管对振幅的增加进行限制。
图2是输出电压为2Vrms，振荡频率为1kHz的振荡电路的例子。
电路的输出阻抗为600Ω。
负反馈量减小放大器的环路增益。
振荡电路的谐波失真率约为0.5％，开机后振幅会不断增大，约需5ms才会稳定下来。
这种振荡电路存在振幅会因R1和R2的误差或者C1和C2的误差而变化，这是这种振荡电路的不足之处。
例如在图3的电路中若R=2.2kΩ，将C2从0.015μF变为0.016μF，振荡电路的振幅会以7Vrms变成9.3Vms．这种振荡电路可振荡的频率范围很宽．可以从数赫兹到数百赫兹。

lf353工作原理
lf353工作原理
LF353是一款专用的宽带高速运算放大器。
该芯片由两个独立的、高性能的运算放大器组成，具有低噪声、高增益带宽和高输入电阻等特点。
它被广泛应用于精密量测和高保真音频放大器等领域。
LF353的工作原理基于差分对输入的放大器电路。
每个运算放大器由一个输入级、一个差动放大级和一个输出级组成。
输入级对输入信号进行阻抗扩展，并将信号传递给差动放大级。
差动放大器使用两个晶体管配对，将差分输入信号放大，并通过输出级将放大的信号输出。
在工作时，差分输入信号被分别连接到运放的非反相和反相输入端。
当输入信号的差异引起非线性失真时，差动放大器会通过增益控制来抵消这种失真。
差动放大器的增益与输出信号的相位差紧密相关，从而实现了对输入信号的线性放大。
LF353还具有高输入阻抗，这意味着它对输入信号的负载影响很小，从而使得输入信号的失真减小。
同时，该芯片的低噪声特性使其能够接收较小幅度的输入信号，并输出高保真度的放大信号。
总之，LF353的工作原理基于差分输入的放大器电路结构，通过差动放大器将输入信号放大，并通过输出级输出放大信号。
它的高增益带宽、低噪声和高输入阻抗等特性使其成为广泛应用于各种精密测量和音频放大器应用的理想选择。

Analog and Interface Integrated Circuits
Operational Amplifiers
Motorola offers a broad line of bipolar operational amplifiers to meet a wide range of applications. From low–cost industry–standard types to high precision circuits, the span encompasses a large range of performance capabilities. These Analog integrated circuits are available as single, dual and quad monolithic devices in a variety of temperature ranges and package ห้องสมุดไป่ตู้tyles. Most devices may be obtained in unencapsulated ‘‘chip’’ form as well. For price and delivery information on chips, please contact your Motorola Sales Representative or Distributor.
Amplifiers and Comparators
In Brief . . .
For over two decades, Motorola has continually refined and updated integrated circuit technologies, analog circuit design techniques and processes in response to the needs of the marketplace. The enhanced performance of newer operational amplifiers and comparators has come through innovative application of these technologies, designs and processes. Some early designs are still available but are giving way to the new, higher performance operational amplifier and comparator circuits. Motorola has pioneered in JFET inputs, low temperature coefficient input stages, Miller loop compensation, all NPN output stages, dual–doublet frequency compensation and analog “in–the–package” trimming of resistors to produce superior high performance operational amplifiers and comparators, operating in many cases from a single supply with low input offset, low noise, low power, high output swing, high slew rate and high gain–bandwidth product at reasonable cost to the customer. Present day operational amplifiers and comparators find applications in all market segments including motor controls, instrumentation, aerospace, automotive, telecommunications, medical, and consumer products.
