低档运放JRC4558。
这种运放是低档机器使用得最多的。
现在被认为超级烂，因为它的声音过于明亮，毛刺感强，所以比起其他的音响用运放来说是最差劲的一种。
不过它在我国暂时应用得还是比较多的,很多的四、五百元的功放还是选择使用它，因为考虑到成本问题和实际能出的效果,没必要选择质量超过5532以上的运放。
对于一些电脑有源音箱来说，它的应付能力还是绰绰有余的。
运放之皇5532。
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。
5532原来是美国SIGNE公司的产品，所以质量最好的是带大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，只须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的封装和4558一样，都是DIP8脚双运放（功能引脚见图），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。

EquipmentThe LM4040series of shunt voltage references are versatile,easy-to-use references that cater to a vast array of applications.The2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads.Additionally,the reference offers low dynamic impedance,low noise,and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures.The LM4040uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances,ranging from0.1%(max)for the A grade to1%(max)for the D grade.Thus,a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications.Packaged in space-saving SC-70and SOT-23-3packages and requiring a minimum current of45µA(typ),the LM4040also is ideal for portable applications.The LM4040xI is characterized for operation over an ambient temperature range of–40°C to85°C.The LM4040xQ is characterized for operation over an ambient temperature range of–40°C to125°C.Please be aware that an important notice concerning availability,standard warranty,and use in

stability.However,if an output bypass capacitor is desired,the LM4040is designed to be stable with all capacitive loads.There is a parasitic Schottky diode connected between pins 2and 3of the SOT-23packaged device.Thus,pin 3of the SOT-23package must be left floating or connected to pin 2.The LM4040x-41is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition systems.For 12-bit systems operating from 5-V supplies such as the ADS7842(see Figure 8),the LM4040x-41(4.096V)permits operation with an LSB of 1mV.Figure 8.Data-Acquisition Circuit

INFORMATION(continued)In a typical shunt-regulator configuration(see Figure9),an external resistor,R S,is connected between the supply and the cathode of the LM4040.R S must be set properly,as it sets the total current available to supply the load(I L)and bias the LM4040(I Z).In all cases,I Z must stay within a specified range for proper operation of the reference.Taking into consideration one extreme in the variation of the load and supply voltage(maximum I L and minimum V S),R S must be small enough to supply the minimum I Z required for operation of the regulator,as given by data-sheet parameters.At the other extreme,maximum V S and minimum I L,R S must be large enough to limit I Z to less than its maximum-rated value of15mA.R S is calculated according to Equation1:Figure9.Shunt

LM3404/04HV1.0A Constant Current Buck Regulator for Driving High Power LEDsGeneral DescriptionThe LM3404/04HV are monolithic switching regulators de-signed to deliver constant currents to high power LEDs.Ideal for automotive,industrial,and general lighting applications,they contain a high-side NFET switch with a minimum over-temperature current limit of 1.2A for step-down (Buck)regu-lators.Hysteretic control with controlled on-time coupled with an external resistor allow the converter output voltage to adjust as needed to deliver constant current to series and series-parallel connected LED arrays of varying number and type.Output current dimming via PWM,broken/open LED protection,low-power shutdown and thermal shutdown com-plete the feature set.Featuresn Integrated 1.2A NFETn V IN Range 6V to 42V (LM3404)n V IN Range 6V to 75V (LM3404HV)n 1.2A Output Current Over Temperature n Cycle-by-Cycle Current Limitn No Control Loop Compensation Requiredn Separate PWM Dimming and Low Power Shutdown nSupports all-ceramic output capacitors and capacitor-less outputsn Thermal shutdown protection n SO-8Package Applicationsn LED Drivern Constant Current Source n Automotive Lighting n General Illumination nIndustrial LightingTypical Application20205401Connection Diagram202054028-Lead Plastic SO-8Package NS Package Number M08AADVANCE INFORMATIONOctober 2006LM3404/04HV 1.0A Constant Current Buck Regulator for Driving High Power LEDs©2006National Semiconductor Corporation Physical Dimensionsinches (millimeters)unless otherwise notedSO-8PackageNS Package Number M08ANational does not assume any responsibility for use of any circuitry described,no circuit patent licenses are implied and National reserves the right at any time without notice to change said circuitry and specifications.For the most current product information visit us at .LIFE SUPPORT POLICYNATIONAL’S PRODUCTS ARE NOT AUTHORIZED FOR USE AS CRITICAL COMPONENTS IN LIFE SUPPORT DEVICES OR SYSTEMS WITHOUT THE EXPRESS WRITTEN APPROVAL OF THE PRESIDENT AND GENERAL COUNSEL OF NATIONAL SEMICONDUCTOR CORPORATION.As used herein:1.Life support devices or systems are devices or systems which,(a)are intended for surgical implant into the body,or (b)support or sustain life,and whose failure to perform when properly used in accordance with instructions for use provided in the labeling,can be reasonably expected to result in a significant injury to the user.2.A critical component is any component of a life support device or system whose failure to perform can be reasonably expected to cause the failure of the life support device or system,or to affect its safety or effectiveness.BANNED SUBSTANCE COMPLIANCENational Semiconductor follows the provisions of the Product Stewardship Guide for Customers (CSP-9-111C2)and Banned Substances and Materials of Interest Specification (CSP-9-111S2)for regulatory environmental compliance.Details may be found at:/quality/green.Lead free products are RoHS compliant.National Semiconductor Americas Customer Support CenterEmail:new.feedback@ Tel:1-800-272-9959National SemiconductorEurope Customer Support CenterFax:+49(0)180-5308586Email:europe.support@Deutsch Tel:+49(0)6995086208English Tel:+44(0)8702402171Français Tel:+33(0)141918790National Semiconductor Asia Pacific Customer Support CenterEmail:ap.support@National SemiconductorJapan Customer Support Center Fax:81-3-5639-7507Email:jpn.feedback@ Tel:81-3-5639-7560L M 3404/04H V 1.0A C o n s t a n t C u r r e n t B u c k R e g u l a t o r f o r D r i v i n g H i g h P o w e r L E D s。
