与很多标准运放相似，但它具有更好的噪声性能，优良的输出驱动能力及相当高的小信号带宽，电源电压范围大等特点。

因此很适合应用在高品质和专业音响设备、仪器、控制电路及电话通道放大器。

用作音频放大时音色温暖，保真度高，在上世纪九十年代初的音响界被发烧友们誉为“运放之皇”，至今仍是很多音响发烧友手中必备的运放之一。

NE5532, SA5532, SE5532, NE5532A, SE5532A Internally Compensated Dual Low Noise Operational AmplifierThe 5532 is a dual high-performance low noise operational amplifier. Compared to most of the standard operational amplifiers, such as the 1458, it shows better noise performance, improved output drive capability and considerably higher small-signal and power bandwidths.This makes the device especially suitable for application in high-quality and professional audio equipment, instrumentation and control circuits, and telephone channel amplifiers. The op amp is internally compensated for gains equal to one. If very low noise is of prime importance, it is recommended that the 5532A version be used because it has guaranteed noise voltage specifications.Features•Small-Signal Bandwidth: 10 MHz•Output Drive Capability: 600 W, 10 V RMS•Input Noise V oltage: 5.0nVńHzǸ (Typical)•DC V oltage Gain: 50000•AC V oltage Gain: 2200 at 10 kHz•Power Bandwidth: 140 kHz•Slew Rate: 9.0 V/m s•Large Supply Voltage Range: "3.0 to "20 V •Compensated for Unity Gain•Pb−Free Packages are AvailableSee detailed ordering and shipping information in the package dimensions section on page 7 of this data sheet.ORDERING INFORMATIONSee general marking information in the device marking section on page 6 of this data sheet.DEVICE MARKING INFORMATIONFigure 1.

NE5532最新资料脚步图

NE5532中文资料引脚图NE5532功放：NE5532是高性能低噪声双运算放大器（双运放）集成电路。

与很多标准运放相似，但它具有更好的噪声性能，优良的输出驱动能力及相当高的小信号带宽，电源电压范围大等特点。

因此很适合应用在高品质和专业音响设备、仪器、控制电路及电话通道放大器。

用作音频放大时音色温暖，保真度高，在上世纪九十年代初的音响界被发烧友们誉为“运放之皇”，至今仍是很多音响发烧友手中必备的运放之一。

NE5532生产厂家：TI[TexasInstruments]、ON、PHILIPS、Semiconductor...NE5532描述：The NE5532， NE5532A， SA5532， and_SA5532A devices are high-performance operational amplifiers combining excellent DC and_AC characteristics.They feature very low noise， high output-drive capability， high unity-gain and_maximum-output-swing bandwidths， low distortion， high slew rate，input-protection diodes， and_output short-circuit protection. These operational amplifiers are compensated internally for unity-gain operation. These devices have specified maximum limits for equivalent input noise voltage.NE5532特性：Equivalent Input Noise Voltage:5 nV/√Hz Typ at 1 kHzUnity-Gain Bandwidth: 10 MHz TypCommon-Mode Rejection Ratio: 100 dB TypHigh DC Voltage Gain: 100 V/mV TypPeak-to-Peak Output Voltage Swing 26 V Typ With VCC± = ±15 V and_RL = 600 ?High Slew Rate: 9 V/μs TypNE5532相关型号：NE5532p、NE5532、NE5532A、SA5532、SA5532、ARC4558、JRC4558D、NE4558、OP275、EL2244、AD827你是不是在找？1、NE5532前置放大电路图2、NE5532前置3、NE5532放大4、NE5532电路5、NE5532芯片怎么用6、NE5532前级电路图7、NE5532负反馈电容8、5532运放2604哪个好9、NE5532p10、NE5532p用什么代换11、NE5532封装12、NE5532前级电路图经典13、opa2604运放比5532好吗NE5532相关运放：1、LM833N BJT工艺双运放噪声4.5nV/√Hz GBW:15M 压摆率:7V/uS 输入失调电压:0.3mV 温漂:2.0uV/℃2、OPA627 BJT工艺单运放噪声4.5nV/√Hz GBW:16M 压摆率:55V/uS 输入失调电压:0.13mV 温漂:1.2uV/℃3、OPA2604 FET工艺双运放噪声10nV//√Hz GBW:20M 压摆率:25V/uS 输入失调电压:1mV 温漂:8uV/℃4、NE5534 BJT工艺单运放噪声3.5nV/√Hz GBW:10M 压摆率:13V/uS 输入失调电压:0.5mV 温漂:规格书未给出5、NE5532 BJT工艺双运放噪声5nV/√Hz GBW:10M 压摆率:9V/uS 输入失调电压:0.5mV 温漂:规格书未给出代替NE5532，NE5532用什么代替?NE5532是双路低噪声高速音频运算放大器，op275:和5532比，胆性还重一点，解析力、低频、音场更好一点，可以买贴片的来打磨声卡用（特别是创新的），可以改善硬冷的数码声。

NE5532介绍ne5532

NE5532介绍ne5532话题：ne5532 通报批评低频NE5532，如果有谁还没有听说过它名字的话，那就还未称得上是音响爱好者。

这个当年有运放皇之称的NE5532，与LM833、LF353、CA3240一起是老牌四大名运放，不过现在只有5532应用得最多。

5532现在主要分开台湾、美国和PHILIPS生产的，日本也有。

最好的是带大S标志的美国产品，市面上要正宗的要卖8元以上，自从SIGNE被PHILIPS 收购后，生产的5532商标使用的都是PHILIPS商标，质量和原品相当，只需4－5元。

而台湾生产的质量就稍微差一些，价格也最便，两三块便可以买到了。

NE5532的封装是DIP8脚双运放，5532的内部为JFET（结型场效应管结构）,声音特点总体来说属于温暖细腻型，驱动力强，但高音略显毛糙，低音偏肥。

以前不少人认为它有少许的“胆味”，不过现在比它更有胆味的已有不少，相对来说就显得不是那么突出了。

5532的电压适应范围非常宽，从正负3V至正负20V 都能正常工作。

它虽然是一个比较旧的运放型号，但现在仍被认为是性价比最高的音响用运放。

是属于平民化的一种运放，被许多中底档的功放采用。

不过现在有太多的假冒NE5532，或非音频用的工业用品，由于5532的引脚功能和4558的相同，所以有些不良商家还把4558擦掉字母后印上5532字样充当5532，一般外观粗糙，印字易擦掉，有少许经验的人也可以辨别。

据说有8mA的电流温热才是正宗的音频用5532。

NE5532还有两位兄弟NE5534和NE5535。

5534是单运放，由于它分开了单运放，没有了双运放之间的相互影响，所以音色不但柔和、温暖和细腻，而且有较好的音乐味。

它的电压适应范围也很宽，低到正负5V的电压也能保持良好的工作状态。

由于以前著名的美国BGW-150功放采用5534作电压激励时，特意让正电源电压高出0.7V，迫使其输出管工作于更完美的甲类状态，使得音质进一步改善，所以现在一般都认为如果让正电源高出0.7V音质会更好。

整个系统在调试时 ,分部分调试. 首先是电源的调试 ,其次是前置放大级和转换电路的调试 ,然后是功率级本身的调试 ,最后将整个电路连接起来调试.
(1) 额定功率 POR : 输入 1 k Hz 正弦波 ,用示波器测到此时输出波形电压有效值为 U = 12. 7 V ,则 POR = U 2/ RL = 12. 72/ 10 = 16. 1 W.

(1) 输出功率要大. 输出功率 PO = U O × IO ,要获得大的输出功率 ,不仅要求输出电压高 ,而且要求输出电流大. 因此 ,晶体管工作在大信号极限运行状态 ,应用时要考虑管子的极限参数 ,注意管子的安全.
(2) 效率要高. 放大信号的过程就是晶体管按照输入信号的变化规律 ,将直流电源提供的能

NE5532功放说到小功率的耳放，不得不提到20世纪的运放之王NE5532，曾经出现在无数的优秀前级放大、调音电路之中，中频温暖细腻厚实，胆味十足，性价比很高!直到今天我们还能很容易地在一些中低档的音响产品中找到它。

由于其体积小、电路简单，所以是讲究实用性、低投入的动手派的首选。

因为NE5532从面世到如今已历经数载，大家对其电路也非常熟悉，有着多种多样的玩法。

在此介绍的耳放的特点是简单、功率小，侧重的是制作的过程。

一、原理分析NE5532是典型的双极型输入运算放大器，用单个NE5532组成的小功率电路有很多版本，本人通过不断地对比和思考，对那些五花八门的电路图作了修改，最终确定了原理图(图1)。

放大倍数是由R3(R4)和R5(R6)来控制的，理论上说如果R3(R4)为1kΩ，R5(R6)为100kΩ，则其放大倍数为100倍，但对于耳放来说，这会引起自激，再说就算真的能达到100倍，效果也不可能好，所以这个电路用于前级时也最好别调成100倍。

当然，对于耳放定2～3倍可以让负反馈适量、音质柔和、清晰更通透，但放大倍数也不能太小，否则也会影响音质，大家可以反复调试，达到自己满意的效果。

笔者是将R3(R4)定为1kΩ，R5(R6)定为20 kΩ，即2倍。

C5(C6)是输入回路的对地通路，在用于耳放电路时应该加大，原理图中的值为22 uF，但用于此耳放应该加大到100 uF。

在这里值得一提的是电源问题，如果你是使用的稳压电源，要注意稳压电源的滤波要给足，因为本电路本身就非常简单，那么对元器件的选取就比较挑剔，建议在选材时尽量选择质量好一点的元器件。

二、PCB绘制笔者使用Protel 99 SE进行布线设计，大家看到的这个PCB图(图2)是我画的第三版，也是我最满意的一版，前几版都存在着飞线，而这一版是没有的，网上的很多版本都存在着飞线的问题，这对挑剔的动手派是不能容忍的。

由于面积小，所以在接地方面要尽量争取一点接地，输入和输出端也可以根据实际情况进行改动。

NE5532制作的唱头放大器MMMC

NE5532制作的唱头放大器MMMC
输入均衡器放大器的设计。

在使用New Japan Radio的NJM5532的电路中，RIAA常数被假定为在New Japan Radio应用电路示例中示出。

（1M，100K，0.003μ，750P组合）
NJM5532具有2个运算放大器电路，因此仅需要一个IC。

电源的电压通常为运算放大器的电源电压的±15V，但是由于它是微弱电压的放大器电路，因此有必要尽可能抑制电源的纹波，因此使其成为稳定的电源。

对于此处使用的电路，IC（串联稳压器）也可以在市场上买到，因此+电源（7815）和电源（7915）都各使用一个。

该IC通常用作电子电路的电源，无需调节即可获得指定的电压。

如果提供给已经制造的功率放大器的信号为100 mV，则MC型唱头的输出约为0.5 mV（对于MM型，约为5 mV），因此必须将其放大200倍左右。

在低频范围内变为10倍以上。

由于RIAA曲线具有足够的NFB曲线，因此可以获得具有较小偏差的频率特性，但是，如果该电路是分立的结构（在晶体管两级放大的情况下），则NFB的数量可能会变得不足。

有必要篡改（正确）RIAA网络常数（低频侧）。

在这方面，运算放大器具有非常大的裸增益（100 dB），因此可以获得设计的频率特性。

....（^^;）也许？
使用容量比功率放大器小的功率变压器，功率滤波电容器和整流二极管。

然后，设计该均衡放大器，以便可以用跳线来切换放大器的增益和输入电阻，以使其对应于MM型盒。
