目前常用的DA芯片

目前常用AD/DA芯片简介目前生产AD/DA的主要厂家有ADI、TI、BB、PHILIP、MOTOROLA等，武汉力源公司拥有多年从事电子产品的经验和雄厚的技术力量支持，已取得排名世界前列的模拟IC生产厂家ADI、TI公司代理权，经营全系列适用各种领域/场合的AD/DA器件。

1. AD公司AD/DA器件耗仅是1mW。

AD7705是基于微控制器（MCU）、数字信号处理器（DSP）系统的理想电路，能够进一步节省成本、缩小体积、减小系统的复杂性。

应用于微处理器（MCU）、数字信号处理（DSP）系统，手持式仪器，分布式数据采集系统。

2）3V/5V CMOS信号调节AD转换器：AD7714AD7714是一个完整的用于低频测量应用场合的模拟前端，用于直接从传感器接收小信号并输出串行数字量。

它使用Σ-Δ转换技术实现高达24位精度的代码而不会丢失。

输入信号加至位于模拟调制器前端的专用可编程增益放大器。

调制器的输出经片内数字滤波器进行处理。

数字滤波器的第一次陷波通过片内控制寄存器来编程，此寄存器可以调节滤波的截止时间和建立时间。

AD7714有3个差分模拟输入（也可以是5个伪差分模拟输入）和一个差分基准输入。

单电源工作（+3V或+5V）。

因此，AD7714能够为含有多达5个通道的系统进行所有的信号调节和转换。

AD7714很适合于灵敏的基于微控制器或DSP的系统，它的串行接口可进行3线操作，通过串行端口可用软件设置增益、信号极性和通道选择。

AD7714具有自校准、系统和背景校准选择，也允许用户读写片内校准寄存器。

CMOS结构保证了很低的功耗，省电模式使待机功耗减至15μW（典型值）。

3）微功耗8通道12位AD转换器：AD7888AD7888是高速、低功耗的12位AD转换器，单电源工作，电压范围为2.7V～5.25V，转换速率高达125ksps，输入跟踪-保持信号宽度最小为500ns，单端采样方式。

AD7888包含有8个单端模拟输入通道，每一通道的模拟输入范围均为0～Vref。

基因组大作业

基因工程作业一、选题背景人血清白蛋白（Human Serum Albumin，简称HSA）是人血浆中的蛋白质，其非糖基化的单链多肽包含585个氨基酸，分子量为66kD。

在血浆中其浓度为42g/L，约占血浆总蛋白的60%。

在体液中人血清白蛋白可以运输脂肪酸、胆色素、氨基酸、类固醇激素、金属离子和许多治疗分子等：同时维持血液正常的渗透压。

在临床上人血清白蛋白可用于治疗休克与烧伤，用于补充因手术、意外事故或大出血所致的血液丢失，也可以作为血浆增容剂。

人血清白蛋白作为血浆容量扩充剂用途广泛，是当前的研究热点之一由于人血清白蛋白在临床上应广泛，市场巨大。

现在临床上人血清白蛋白主要是靠收集人的血液通过分级过滤获得，面对如此巨大的需求量，单靠人血液提取人血清白蛋白是难以满足的，同时，人血来源极其复杂，容易导致污染，如肝炎病毒，爱滋病毒等。

为了缓解这些矛盾，通过基因工程技术把人血清白蛋白基因克隆到微生物(细菌，真菌等)，动物，植物宿主上进行高效表达是最具有前景的方法，现对重组人血清白蛋白在不同表达系统中的研究进展作一简要综述[43] 目前也有用酵母等低等真核生物表达rHSA，如酿酒酵母，甲醇利用型酵母等。

其中巴斯德毕赤酵母由于分泌蛋白含量高、表达稳定，成为目前人们普遍采用的rHSA表达宿主。

常用大功率D类音频功放IC芯片选型说明

常⽤⼤功率D类⾳频功放IC芯⽚选型说明常⽤⼤功率Ｄ类⾳频功放IC芯⽚选型说明传统⼤功率功放芯⽚，⼀般都是模拟的功放芯⽚，象⼤家都熟悉的TDA2030、LM1875、TDA1521等。

这些功放除了⾳质会好⼀点，其它的对于现在的D类功放来说，都是缺点。

如今随着技术的进步，D 类功放的⾳质技术早已突破，⽐传统功放芯⽚差不了多少。

以HX8330为代表的D类功放，是替代这些优秀的前辈产品不⼆之选。

⼆、模拟功放的缺点：●电源供电⼀般都要⽤正负双电源供电。

●⼤部分都是插件式。

●因本⾝发热严重，需要带⼀块沉重的铝⽚散热。

●占⽤PCB板和机壳的空间很⼤。

●外围元件多，特别是电解电容也⽤的多。

三、HX8330概述：HX8330是⼀款30W⾼效D类⾳频功率放⼤电路，主要应⽤于⾳响等消费类⾳频设备。

此款电路可以驱动低⾄4Ω负载的⽴体声扬声器，功效⾼达90%，使得在播放⾳乐时不需要额外的散热器。

其特点如下：●15W功率输出(12V电压，4Ω负载，TND+N=10%）；●30W功率输出（16V电压，4Ω负载，TND+N=10%）；●效率⾼达90%，⽆需散热⽚；●较⼤的电源电压范围8V~20V；●免滤波功能，输出不需要电感进⾏滤波；●输出管脚⽅便布线布局；●良好短路保护和具备⾃动恢复功能的温度保护；●良好的失真；●增益36dB；●差分输⼊；●简单的外围设计；QQ:1207435600●封装形式：ESOP8。

四、应⽤领域：●拉杆⾳箱:●⼤功率喊话器:●落地⾳箱:●蓝⽛⾳箱●扩⾳器五、芯⽚对⽐分析：六、功能框图与引脚说明：七、应⽤原理图：如上图，可以很清晰的看出硬件的外围电路是极其简单的，bom成本低廉⼋、HX8330优势说明：1、外围元件少，电路简单,2、效率⾼达90%，⽆需散热⽚3、占⽤PCB板空间⼩4、16V供电时，功率可以到达30W九、总结：我写这边⽂章的⽬的，并不是想要抵扉传统的模拟功放。

只是想告诉各位同仁，在如今市场竞争激烈的环境下，⼀个成品的利润能多铮⼏⽑钱，都是⼀件不容易的事。

across the output-stage transistors.The two components of this internal voltage drop are the headroom or dc voltage drop that varies inversely to output power,and the sinewave nature of the output.The total voltage drop can be calculated by subtracting the RMS value of the output voltage from V DD .The internal voltage drop multiplied by the average value of the supply current,I DD (avg),determines the internal power dissipation of the amplifier.Figure 35.Voltage and Current Waveforms forAn easy-to-use equation to calculate efficiency starts BTL Amplifiers out as being equal to the ratio of power from the power supply to the power delivered to the load.To accurately calculate the RMS and average values of Although the voltages and currents for SE and BTL power in the load and in the amplifier,the current and are sinusoidal in the load,currents from the supply voltage waveform shapes must first be understood are different between SE and BTL configurations.In (see Figure 35).an SE application the current waveform is a half-wave rectified shape,whereas in BTL it is a full-wave rectified waveform.This means RMS conversion factors are different.Keep in mind that for most of the waveform both the push and pull transistors are not on at the same time,which supports the fact that each amplifier in the BTL device only draws current from the supply for half the waveform.The

If either speaker appears damaged,do not use them. Repack both speakers in the original carton and notify your authorized Bose dealer immediately.CAUTION:T o avoid danger of suffocation,keep the plastic bag that wraps these speakers out of reach of babies and children. The thin film may cling to nose and mouth and prevent breathing.Figure 1The product label on the bottom of the speaker indicates if it goes on the left or the right side of your room.Figure 2Ideal placement in an average-sizedroom.CAUTION:Bose 701 speakers are notintended to hang from walls, orto stand on shelves or tables.They are designed asfloorstanding speakers only.T o prevent injury to children andpets, and to protect yourspeaker investment, do notplace your 701 speakers in hightraffic areas where they can beaccidentally knocked over. Where to stand the speakersThe product label on the bottom of each speaker indicates “Left” or “Right” (Figure 1). Forbest acoustic performance, stand the left speaker on the left side of your room. Stand theright speaker on the right side.Place the speakers 6 to 20 feet (1.8 - 6 m) apart and at least 2 feet (.6 m) from side walls(Figure 2). Make sure each speaker is at least 2 feet (.6 m) from your TV screen, to preventvideo interference.For more bass response, move your speakers closer to the walls of your room. T o reducebass response, move them farther from the walls. This will soften heavy or booming bass.Attention: Be sure to place each speaker at least 2" (5cm) from the wall behind it. For thebest performance, it is important not to block the acoustic port at the rear of eachspeaker.AM172642_03_V.pdf December 20, 20015Choose the speaker cordIt is important to use the proper gauge (thickness) of speaker cord. Standard zip cord (2-conductor, 18-gauge wire) is recommended for most applications. Y ou can find this wire at most electrical and hardware stores.You will need thicker wire if your speakers will be more than 30 feet from a receiver or amplifier. Refer to the “Wire recommendations” under “Technical Information,” or contact your authorized Bose® dealer for more information.T o run speaker wire through a wall or under a floorMake sure you have enough wire to reach from the receiver to each speaker. Also check your local building code requirements. Before proceeding, you may want to contact an electrical installer for information about your local building or safety regulations.Prepare the cordSpeaker cord consists of two insulated wires. The insulation around one wire is marked (striped, collared, or ribbed). This marked wire is always positive (+). The plain wire is always negative (–). These wires correspond to the red (+) and black (–) terminals on the speaker, receiver, or amplifier.Note: It is sometimes difficult to distinguish wire markings. Inspect both wires carefully. To prepare ends of cord:1.Strip approximately 1⁄2 inch (12 mm) of insulation from both wires.2.Twist the bare ends of each wire.Make the connectionsJust press down the terminal tab on the bottom of each speaker to insert the appropriate wire (Figure 3).1.Connect one cord to the right speaker output of your receiver or amplifier.a.Attach the marked wire at one end to the red (+) terminal.b.Attach the plain wire at that end to the black (–) terminal.2.Connect the other end of the same cord to your right speaker.a.Attach the marked wire to the red (+) terminal.b.Attach the plain wire to the black (–) terminal.3.Connect the second cord to the left speaker output and left speaker. Follow theprocedure described above.Note:Be careful when using stranded wire. Loose strands should not touch across terminals.CAUTION:Before making any connections, turn off your receiver or amplifier and unplug from outlet (the AC power mains). Not doing so may result in damage to your system. CAUTION:Never use broken or frayed wiring, as electrical shock or damage may result.6December 20, 2001 AM172642_03_V.pdfAM172642_03_V .pdf December 20, 20017Check the connectionsMake sure that no loose strands of wire touch across terminals. Bridged wires can short circuit and damage the speakers or components. Tighten any loose connections before you plug in the receiver or amplifier and turn it on.T est the connectionsTo make sure your speakers operate correctly:1.Set your receiver or amplifier for MONO (monophonic) and turn it on.2.Set the balance control to normal (center position).3.Place the speakers less than 6 inches (15 cm) apart, facing each other.4.Play some deep bass passages of music through the speakers.The sound should seem to come from a point between the two speakers. The bass should be full and natural. If it is not, your connections may be out of phase. T o correct the problem, reverse the connections on the back of one speaker. Then repeat steps 1 - 4.Left SpeakerFigure 3T o complete the speaker connec-tions.8December 20, 2001 AM172642_03_V .pdfSolutionOne speaker doesn’t play or sounds distorted.Possible cause Defective amplifier or receiver channel, or defective speaker.How to find outDisconnect the cords from both speakers. Then switch them, connecting the right speaker cord to the leftspeaker and the left speaker cord to the right speaker.If the previously “broken”speaker now plays properly,and the other one does not,one channel in the amplifier or receiver is probably defective.If the original speaker still does not play properly, call Bose or your retailer to arrange for service.High sound volume drops suddenly.The automatic system protection circuit has activated to protect the speakers from electrical stress or overload.Both speakers do not play or sound distorted.Defective amplifier or receiver.Disconnect the amplifier or receiver from the speakers.Reconnect the speakers to another amplifier or receiver that is working properly.Return the volume to a reason-able level and avoid extremely high volume settings.Lower the volume. If it returns to normal, your speakers’ automatic protection circuit caused the sudden drop. This volume reduction protects the speakers from electronic stress and overload.ProblemT o clean your speakersWipe the 701® speaker cabinets clean using a soft cloth dampened with a mild detergent.No other regular maintenance is required.How to troubleshoot problemsIf you have a problem with your 701 speakers:1.Turn off the amplifier or receiver and check all the connections between the speakers,amplifier, or receiver.
