LM10中文资料

LM10Operational Amplifier and Voltage ReferenceGeneral DescriptionThe LM10series are monolithic linear ICs consisting of a precision reference,an adjustable reference buffer and an independent,high quality op amp.The unit can operate from a total supply voltage as low as 1.1V or as high as 40V,drawing only 270µA.A complemen-tary output stage swings within 15mV of the supply termi-nals or will deliver ±20mA output current with ±0.4V satura-tion.Reference output can be as low as 200mV.The circuit is recommended for portable equipment and is completely specified for operation from a single power cell.In contrast,high output-drive capability,both voltage and current,along with thermal overload protection,suggest it in demanding general-purpose applications.The device is capable of operating in a floating mode,inde-pendent of fixed supplies.It can function as a remote com-parator,signal conditioner,SCR controller or transmitter foranalog signals,delivering the processed signal on the same line used to supply power.It is also suited for operation in a wide range of voltage-and current-regulator applications,from low voltages to several hundred volts,providing greater precision than existing ICs.This series is available in the three standard temperature ranges,with the commercial part having relaxed limits.In ad-dition,a low-voltage specification (suffix “L”)is available in the limited temperature ranges at a cost savings.Featuresn input offset voltage: 2.0mV (max)n input offset current:0.7nA (max)n input bias current:20nA (max)n reference

current260400280500µA500570µA Note1:Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.Operating Ratings indicate conditions for which the device is func-tional,but do not guarantee specific performance limits.Note2:The Input voltage can exceed the supply voltages provided that the voltage from the input to any other terminal does not exceed the maximum differential input voltage and excess dissipation is accounted for when V IN<V−.Note3:The maximum,operating-junction temperature is150˚C for the LM10,100˚C for the LM10B(L)and85˚C for the LM10C(L).At elevated temperatures,devices must be derated based on package thermal resistance.Note4:Internal thermal limiting prevents excessive heating that could result in sudden failure,but the IC can be subjected to accelerated stress with a shorted output and worst-case conditions.Note5:These specifications apply for V−≤V CM≤V+−0.85V(1.0V),1.2V(1.3V)<V S≤V MAX,V REF=0.2V and0≤I REF≤1.0mA,unless otherwise specified:V MAX=40V for the standard part and6.5V for the low voltage part.Normal typeface indicates25˚C limits.Boldface type indicates limits and altered test conditions for full-temperature-range operation;this is−55˚C to125˚C for the LM10,−25˚C to85˚C for the LM10B(L)and0˚C to70˚C for the LM10C(L).The specifications do not include the effects of thermal gradients(τ1≅20ms),die heating(τ2≅0.2s)or package heating.Gradient effects are small and tend to offset the electrical error(see curves).Note6:For T J>90˚C,I OS may exceed1.5nA for V CM=V−.With T J=125˚C and V−≤V CM≤V−+0.1V,I OS≤5nA.Note7:This defines operation in floating applications such as the bootstrapped regulator or two-wire transmitter.Output is connected to the V+terminal of the IC and input common mode is referred to V−(see typical applications).Effect of larger output-voltage swings with higher load resistance can be accounted for by adding the positive-supply rejection error.Note8:Refer to RETS10X for LM10H military specifications.Definition of TermsInput offset voltage:That voltage which must be applied between the input terminals to bias the unloaded output in the linear region.Input offset current:The difference in the currents at the in-put terminals when the unloaded output is in the linear re-gion.Input bias current:The absolute value of the average of the two input currents.Input resistance:The ratio of the change in input voltage to the change in input current on either input with the other grounded.Large signal voltage gain:The ratio of the specified output voltage swing to the change in differential input voltage re-quired to produce it.Shunt gain:The ratio of the specified output voltage swing to the change in differential input voltage required to produce it with the output tied to the V+terminal of the IC.The load and power source are connected between the V+and V−ter-minals,and input common-mode is referred to the V−termi-nal.Common-mode rejection:The ratio of the input voltage range to the change in offset voltage between the extremes.Supply-voltage rejection:The ratio of the specified supply-voltage change to the change in offset voltage be-tween the extremes.Line regulation:The average change in reference output voltage over the specified supply voltage range.Load regulation:The change in reference output voltage from no load to that load specified.Feedback sense voltage:The voltage,referred to V−,on the reference feedback terminal while operating in regula-tion.Reference amplifier gain:The ratio of the specified refer-ence output change to the change in feedback sense voltage required to produce it.Feedback current:The absolute value of the current at the feedback terminal when operating in regulation.Supply current:The current required from the power source to operate the amplifier and reference with their out-puts unloaded and operating in the linear range.4Typical Performance Characteristics(Op

The key parameters are desired motor torque and velocity. While the motor holding torque describes the torque at stand-still, and gives a good indication for comparing different motors, it is not the key parameter for the best fitting motor. The required torque is a result of static load on the motor, dynamic loads which occur during acceleration/deceleration and loads due to friction. In most applications the load at maximum desired motor velocity is most critical, because of the reduction of motor torque at higher velocity. While the required velocity generally is well known, the required torque often is only roughly known. Generally, longer motors and motors with a larger diameter deliver a higher torque. But, using the same driver voltage for the motor, the larger motor earlier looses torque when increasing motor velocity. This means, that for a high torque at a high motor velocity, the smaller motor might be the better fitting solution.Please refer to the torque vs. velocity diagram to determine the best fitting motor, which delivers enough torque at your desired velocities.6.1.1Determining the maximum torque requiredTry a motor which should roughly fit. Take into consideration worst case conditions, i.e. minimum driver supply voltage and minimum driver current, maximum or minimum environment temperature (whichever is worse) and maximum friction of mechanics. Now, consider that you want to be on the safe side, and add some 10 percent safety margin taking into account unknown degradation of mechanics and motor.6.2Motor current settingBasically, the motor torque is proportional to the motor current, as long as the current stays at a reasonable level. At the same time, the power consumption of the motor (and driver) is proportional to the square of the motor current. Optimally, the motor should be chosen to bring the required performance at the rated motor current. For a short time, the motor current may be raised above this level in order to get increased torque, but care has to be taken in order not to exceed the maximum coil temperature of 130°C respectively a continuous motor operation temperature of 90°C.Table 6.1: Motor current settings6.2.1Choosing the optimum current settingGenerally, you choose the motor in order to give the desired performance at nominal current. For short time operation, you might want to increase the motor current to get a higher torque than specified for the motor. In a hot environment, you might want to work with a reduced motor current in order to reduce motor self heating.The TRINAMIC drivers allow setting the motor current for up to three conditions:-Stand still (choose a low current)-Nominal operation (nominal current)-High acceleration (if increased torque is required: You may choose a current above the nominal setting, but be aware, that the mean power dissipation shall not exceed the motors nominal rating)If you reach the velocity limit, it might be a good idea to reduce the motor current, in order to avoid resonances occurring. Please refer to the information about choosing the driver voltage.6.2.2Choosing the standby currentMost applications do not need much torque during motor stand-still. You should always reduce motor current during stand still. This reduces power dissipation and heat generation. Depending on your application, you typically at least can half power dissipation. There are several aspects why this is possible: In standstill, motor torque is higher than at any other velocity. Thus, you do not need the full current even with a static load! Your application might need no torque at all, but you might need to keep the exact microstep position. Try how low you can go in your application. If the microstep position exactness does not matter for the time of standstill, you might even reduce the motor current to zero, provided that there is no static load on the motor and enough friction in order to avoid complete position loss.6.3Motor driver supply voltageThe driver supply voltage in many applications cannot be chosen freely, because other components have a fixed supply voltage of e.g. 24V DC. If you have possibility to choose the driver supply voltage, please refer to the driver data sheet, and consider that a higher voltage means a higher torque at higher velocity. The motor torque diagrams are measured for a given supply voltage. You typically can scale the velocity axis (steps/sec) proportionally to the supply voltage to adapt the curve, e.g. if the curve is measured for 48V and you consider operation at 24V, half all values on the x-Axis to get an idea of the motor performance.For a chopper driver, consider the following corner values for the driver supply voltage (motor voltage). The table is based on the nominal motor voltage, which normally just has a theoretical background in order to determine the resistive loss in the motor.Comment on the nominal motor voltage: Array(Please refer to motor technical data table.)Table 6.2: Driver supply voltage considerations6.3.1Determining if the given driver voltage is sufficientTry to brake the motor and listen to it at different velocities. Does the sound of the motor get raucous or harsh when exceeding some velocity? Then the motor gets into a resonance area. The reason is that the motor back-EMF voltage reaches the supply voltage. Thus, the driver cannot bring the full current into the motor any more. This is typically a sign, that the motor velocity should not be further increased, because resonances and reduced current affect motor torque.Measure the motor coil current at maximum desired velocityFor microstepping: If the waveform is still basically sinusoidal, the motor driver supply voltage is sufficient.For Fullstepping: If the motor current still reaches a constant plateau, the driver voltage is sufficient.If you determine, that the voltage is not sufficient, you could either increase the voltage or reduce the current (and thus torque).6.4Back EMF (BEMF)Within SI units, the numeric value of the BEMF constant has the same numeric value as the numeric value of the torque constant. For example, a motor with a torque constant of 1 Nm/A would have a BEMF constant of 1V/rad/s. Turning such a motor with 1 rps (1 rps = 1 revolution per second = 6.28 rad/s) generates a BEMF voltage of 6.28V.The Back EMF constant can be calculated as:is multiplied by 2 in this The voltage is valid as RMS voltage per coil, thus the nominal current INOMformula, since the nominal current assumes a full step position, with two coils switched on. The torque is in unit [Nm] where 1Nm = 100cNm = 1000mNm.One can easily measure the BEMF constant of a two phase stepper motor with a (digital) scope. One just has to measure the voltage of one coil (one phase) when turning the axis of the motor manually. With this, one gets a voltage (amplitude) and a frequency of a periodic voltage signal (sine wave). The full step frequency is 4 times the frequency the measured sine wave.6.5Choosing the commutation schemeWhile the motor performance curves are depicted for fullstepping and halfstepping, most modern drivers provide a microstepping scheme. Microstepping uses a discrete sine and a cosine wave to drive both coils of the motor, and gives a very smooth motor behavior as well as an increased position resolution. The amplitude of the waves is 1.41 times the nominal motor current, while the RMS values equal the nominal motor current. The stepper motor does not make loud steps any more – it turns smoothly! Therefore, 16 microsteps or more are recommended for a smooth operation and the avoidance of resonances. To operate the motor at fullstepping, some considerations should betaken into account.Table 6.3: Comparing microstepping and fullsteppingMicrostepping gives the best performance for most applications and can be considered as state-of-the art. However, fullstepping allows some ten percent higher motor velocities, when compared to microstepping. A combination of microstepping at low and medium velocities and fullstepping at high velocities gives best performance at all velocities and is most universal. Most Trinamic driver modules support all three modes.6.5.1FullsteppingWhen operating the motor in fullstep, resonances may occur. The resonance frequencies depend on the motor load. When the motor gets into a resonance area, it even might not turn anymore! Thus you should avoid resonance frequencies.6.5.1.1Avoiding motor resonance in fullstep operationDo not operate the motor at resonance velocities for extended periods of time. Use a reasonably high acceleration in order to accelerate to a resonance-free velocity. This avoids the build-up of resonances. When resonances occur at very high velocities, try reducing the current setting.A resonance dampener might be required, if the resonance frequencies cannot be skipped6.6Optimum motor settingsThe following table shows the settings for the highest reachable fullstep velocities.Table 6.4: Optimum motor settings6.6.1Settings for the TRINAMIC TMCL™ modulesFollowing TMCL™ settings apply best for highest motor velocities and smooth motor behavior at low velocities. They are intended for the use with TRINIMICs controller modules.Mixed decay should be switched on constantly. Microstep resolution is 4 (TMCL™), this is 16 times microstepping. The pulse devisor is set to 3. With a 64 microstep setting the same values are valid with the pulse divisor set to 1.Table 6.5: Optimum motor settings for TMCL™ modules (tested with TMCM-110)7Revision history 7.1Documentation revisionTable 7.1: Documentation revision8References[TMCL™] TMCL TM manual, 。

十倍电压放大器电路图大全(前置放大电压跟随器LM386音响功放电路)精选全文完整版

可编辑修改精选全文完整版十倍电压放大器电路图大全（前置放大电压跟随器LM386音响功放电路）电压放大器（VoltageAmplifier）是提高信号电压的装置。

对弱信号，常用多级放大，级联方式分直接耦合、阻容耦合和变压器耦合，要求放大倍数高、频率响应平坦、失真小。

当负载为谐振电路或耦合回路时，要求在指定频率范围内有较好幅频和相频特性以及较高的选择性。

电压放大器工作原理运算放大器的核心是一个具有恒流源的差分放大器，由于恒流源的作用尽量的保证晶体管的工作点，能在晶体管特性曲线比较线性的一段工作，并且采用了深度的负反馈使整个运算放大电路对信号具有较好的线性放大。

一个运算放大器为了保证有一定的增益，都是采用多级直流放大器的组合，在制造时就在一个芯片上完成，以集成电路运算放大器的形式出现；保证了良好的耦合特性及稳定性。

所以运算放大器就是高质量的模拟放大器的代名词。

由于运算放大器的核心是一个差分放大器，所以就有两个输入端，和一个输出端，其在电路图上的表示符号，引脚的位置和电压比较器一样；两个输入端和输出的关系也有同相输入端和反相输入端的称呼。

这两个输入端都可以输入信号（对称的差分信号）；也可以，一个输入端设定为基准电压，一个输入端输入模拟信号。

运算放大器既然能把信号进行放大，显然我们用他来代替电压比较器作为电压比较用也是没有问题的，就有许多电路的电压比较电路就采用了运算放大器电路完成的。

不过运算放大器作为电压比较器使用；其灵敏度、反映速度都要差的多，还是不要这样替代用的为好，但是电压比较器是绝对不能作为运算放大器用的。

在一般的电路原理图上运算放大器和电压比较器，光从符号上很难区分图纸上表示的是运算放大器还是电压比较器，只能通过对电路的分析，进行判断。

十倍电压放大器电路图（一）工频干扰是脑电信号的主要干扰，虽然前置放大电路对共模干扰具有较强的抑制作用，但部分工频干扰是以差模信号方式进入电路的，且频率处于脑电信号的频带之内，加上电极和输入回路不稳定等因素，前级电路输出的脑电信号仍存在较强的工频干扰，所以必须专门滤除。
