4890 资料
4890——1 .2 Watt Audio Power Amplifier●General Description--- The 4890is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1.2 watt of continuous average power to an 8ΩBTL load with less than 1% distortion (THD+N) from a 5V DC power supply.--- The 4890 does not require output coupling capacitors or bootstrap capacitors, and therefore is ideally suited for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.--- The 4890features a low-power consumption shutdown mode, which is achieved by driving the shutdown pin with logic low. Additionally, the CCT4890 features an internal thermal shutdown protection mechanism.●Key Specifications·PSRR at 217Hz, V DD = 5V 65dB (typ.)·Power Output at 5.0V & 1% THD 1.2W (typ.)·Power Output at 3.3V & 1% THD 400mW (typ.)·Shutdown Current 0.1µA (typ.)●Features·Ultra low current shutdown mode·BTL output can drive capacitive loads·Improved pop&click circuitry eliminates noises during turn-on and turn-off transitions ·No output coupling capacitors, snubber networks or bootstrap capacitors required ·Unity-gain stable·External gain configuration capability●Applications·Mobile Phones·PDAs·Portable electronic devices●Operating Ratings·Temperature Range ﹣40℃～85℃·Supply Voltage 2.3V≤V DD≤6.0V●Typical Application●Connection Diagram● Absolute Maximum Ratings·Supply Voltage6.0V·Storage Temperature －65℃～＋150℃ ·Input Voltage －0.3V ～V DD ＋0.3V ·Power Dissipation Internally limited ·ESD Susceptibility （Human body model ） 2000V ·ESD Susceptibility （Machine model ） 200V ·Junction Temperature150℃● Electrical Characteristics （V DD ＝5V ）Unless otherwise specified.

Agilent 490-GC Micro-GC Solution 数据手册
Key BenefitsThe Speed You Need. Precise gas analysis in seconds rather than minutes brings improved product quality and more exact product valuation to industries such as oil and gas exploration, refi ning, natural gas production and distribution, fuel cell development, and specialty gas production.Full Flexibility. The 490-GC Micro-GC is a rugged, compact analyzer for gas quality analysis in thelaboratory, on-line and at-line. With advanced micro-machining and computing technologies, the 490-GC offers between one and four analytical GC channels. Each channel is a separate GC with pneumatics, injector, column, and detector. User exchangeable GC channels or modules provide quick and easy reconfi guration for any application.Increase Monitoring Frequency. Micro-electronic gascontrol with time-programmable backfl ush lets you inject samples while eliminating components that could foul the column and reduce lifetime. Extremely fast analysis for continuous process monitoring and control using the 490-GC ensures faster and better decisions that can lead to higher quality end-products.Easy Start-Up. On arrival, the 490-GC provides the results and ruggedness you demand in the laboratory and in the fi eld for the analysis of gaseous and vapor streams. Start-up is easy, quick and seamless with electronic data sheets (EDS), which store operational history and the last used method for each GC channel. The 490-GC can be controlled from virtually anywhere in the world through a PC and the internet, using industry standard protocols such as TCP/IP.When the composition of gas mixtures is critical, Varian’s 490-GC Micro-GC delivers the information you need, time after time. Our 5th generation micro-gas chromatograph generates more data in less time for faster and better business decisions.Specifi cationsConfi gurationOne to four analytical GC channelsControl• Independent control of each analytical channel• Injector, column, and detector settings• Pneumatics, including time-based column pressure programmingInjector• Micro-machined injector with no moving parts• Injection volume 1 μL to 10 μL, software selectable • Optional heated injector, up to 110 °C, including heated sample transfer line• Optionalbackfl ush capabilityColumn OvenTemperature range, up to 180 °C, isothermalDetector• Micro-machined Thermal Conductivity Detector (TCD)• Dual-channel (sample and reference fl ow)• Internal volume 200 nL per channel• Filaments,4Detection Limits, TCD• WCOT (wall coated open tubular) columns, 1 ppm • Micro-packed/PLOT columns, 10 ppmOperating Range, TCD• Concentration, 1 ppm to 100% level• Linear dynamic range, 106Repeatability< 0.5% RSD for propane at 1 mol % level for WCOT columns at constant temperature and pressure Optional DMD (Differential Mobility Detector) occupies one channel position• Detection limit, 100 ppb for MES• Dynamic range, 103• RSD < 2% at 10 times the LDL• Gas requirements, 400 mL/min ‘Zero’ Air or N2• Source, 63Ni, 5 mCi (185 MBq)Carrier Gas• He,H2, N2, or Ar, 550 ± 10 kPa (80 ± 1.5 psi) input • Up to two different types of carrier gases can be used in one instrument• Inlet connection, 3.2 mm (1/8 in.) stainless steel compression fi tting (Swagelok®)Sampling• Sample inlet, 1.6 mm (1/16 in.) stainless steel Valco® fi tting with replaceable 5 μm stainless steel fi lter • Sample conditions, non-condensing gas of 0 °C to 110 °C• Maximum sample inlet pressure, 100 kPa (14.5 psi)• Software selectable sample pump or continuous fl ow • Optional separate sample inlet can be installed in front or backCommunication• Analog input, 6 signals (0-10 V)• LA N(TCP/IP)• Serial (RS232) for control of a stream selection valve • Webserver, display instrument status on standard Internet browserControl/Data Handling Software• Standard package, Galaxie™ Chromatography Software from Varian• Additional calculation and reporting packages- Natural gas calculations, such as calorifi c valueand relative density, meet ISO 6976, GPA 2171,and ASTM D 3588 standards- Custom calculations and reporting- I/O control, for control of analog output signals(4-20mA) and relays- PCI1000Com, for transferring results fromGalaxie Chromatography Software from Varian,over Modbus TCP/IP to a DCS19 in. housing for a dual channel Micro-GCconfi gurable with a wide range of accessories• Stream selection valves• Micro-Gasifi er• Genie® Membrane Filters• Sample pressure sensorsOptions• Micro-Gasifi er, heated pressure-reducing- Controlled evaporation of LPG or LNG samples- Controlled reduction of high pressure gas samples- Operating temperature 100-150 °C, default set at 100 °C- Sample inlet pressure, 1000 psi/7000 kPa maximum - Sample carry-over, <1% RSD, as measured forhexane- Sample outlet pressure 7.5 psi +/- 2.5 psi• Genie Membrane Filter- Fully inert membrane technology- Compliant for BTU calorifi c value applications- Removes particles from gas samples- Removes liquids from gas samples• Stream Selection Valve, up to 16 sample streams for multi-stream analysis.

LM4890运放电路分析-推荐下载
一、电路图先发个图来看看，这个图是LM4890在MPN中常用到的电路。
二、LM48920介绍1、大概描述LM4890 是一款主要为移动电话和其他便携式通信设备中的应用而设计的音频功率放大器。
在5V 直流供电下，它可以将1W 的功率连续平均功率输出到8Ω的BTL（什么是BTL呢？）负载上，且总的谐波失真小于1%。
Boomer 音频功率放大器是为使用尽可能小的外部组件来提供高质量的输出功率而专门设计的。
LM4890 不需要外部的耦合电容或者自举电容，所以非常适用移动电话和其他低压应用，这些应用中的主要要求是功耗尽可能小。
LM4890 的主要特征是关断模式下功耗低。
当关断引脚的电平为低时即可进入关断模式。
另外，LM4890还有一个特征是内部的热关断保护机制。
LM4890 包含一个特殊电路用来消除从开启到关断转换时产生的噪音。
LM4890 的单位增益是稳定的，它可以通过设置外部的增益电阻来配置。
注：BTL，(Bridge-Tied-load)意为桥接式负载。
负载的两端分别接在两个放大器的输出端。
其中一个放大器的输出是另外一个放大器的镜像输出，也就是说加在负载两端的信号仅在相位上相差180°。
负载上将得到原来单端输出的2倍电压。
从理论上来讲电路的输出功率将增加4倍。
BTL电路能充分利用系统电压，因此BTL结构常应用于低电压系统或电池供电系统中。
在汽车音响中当每声道功率超过10w时，大多采用BTL形式。
BTL形式不同于推挽形式，BTL的每一个放大器放大的信号都是完整的信号，只是两个放大器的输出信号反相而已。
用集成功放块构成一个BTL放大器需要一个双声道或两个单声道的功放块。
但是并不是所有的功放块都适用于BTL形式，BTL形式的几种接法也各有优劣。
典型的功放集成块有TDA2030A LM1875 LM4766 LM3886 TDA1514等。
三、应用说明1、桥式结构的例子如图1 所示，LM4890 内部有两个运算放大器，可以有一些不同的放大器结构。

+5V如何避免EMI和ESD问题？相机安装在工业现场，有一些产生EMI（电磁干扰）的设备，相机本身易于受到ESD（静电放电）影响。
严重的EMI和ESD干扰会造成误触发、突然停止采流等故障。
EMI和ESD同时也会对相机成像质量带来不利影响，并能影响相机与PC间数据传输的可靠性。
为了避免上述EMI和ESD导致的问题，华谷动力建议客户采取如下防范措施：（1）使用高质量的带屏蔽线缆。

符合UL489标准的塑壳式断路器触头系统和 灭弧系统的设计与试验(文献综述)
本科生毕业设计（论文）文献综述题目：符合UL489标准的塑壳式断路器触头系统和灭弧系统的设计与试验姓名：学号：学院：专业：年级：指导教师：2014年03月30日引言：塑壳式断路器也称空气开关或装置式自动开关。
主要用作低压系统的电能的保护和分断。
塑壳断路器主要由主触头系统、灭弧系统、操作机构、脱扣器和外壳等部分组成。
脱扣器接收故障信号，并传递给操作机构，由其控制主触头及辅助触头的断开和闭合。
灭弧室用于熄灭主触头系统在分断电路时产生的电弧。
当断路器出现短路电流并达到整定值时，瞬时脱扣器中的电磁铁动作，推动牵引杆运动，使操作机构脱扣，从而将电路切断。
当电路中出现过载电流时，过载脱扣器中的热双金属受热弯曲，推动牵引杆运动，达到规定时间后操作机构脱扣，将电路切断。
塑壳断路器的UL489标准和IEC标准主要区别在于UL489标准的验证试验更加注重断路器的安全性和寿命，增加了一个6倍过载试验，检验每相温升是否在规定值内，并且其寿命试验的次数为10000次也远大于IEC标准的4000次，来提高断路器的安全性能。
触头系统和灭弧系统是断路器的主要结构。
电动斥力是影响触头系统正常工作的重要因素，触头系统可靠性的高低直接影响了整个断路器的性能。
而同时合理设计的触头灭弧系统内部的结构，使之能获得更强的吹弧磁场和磁吹力，对于提高塑壳断路器的分断性能和安全性能具有重要意义。
磁场中的载流导体必然受到力的作用，这个力企图改变回路的形状，以使环绕的磁通增加[1]。
由于电流产生磁场，因此载流导体之间也要受到力的作用，这种力称为电动力。
电器的触头系统中由于有电流通过，导体之间同样存在着相互作用的电动力。
动、静触头间的电动斥力轻则使触头压力减小，接触电阻增大以至温升升高，重则使触头弹开，产生电弧，加速触头磨损或导致触头熔焊。
因此，研究电动力对设计好塑壳断路器的触头系统和灭弧系统，提高断路器的安全性具有重要意义。
作用在动触头上的电动斥力 F ( 包括导电回路产生的洛仑磁力F及触头间由于电流收缩产生的Holm力)和预压力决定了触头的斥开时间和打开速度，从而对塑壳断路器的限流性能产生重要的影响。
