  • Optimal+Long-Term+Operation

    This  book  deals with a very important problem in power system planning for countries in which hydrogeneration accounts for the greatest  part  of  the system power production. During the past thirty years many techniques have been developed to cope with the long-term operation  of  hydro reser- voirs. These techniques have been discussed in a number  of  publications, but  they have  not  until now been documented  in  book  form.

  • 高速放大器技術(shù)

      This publication represents the largest LTC commitmentto an application note to date. No other application noteabsorbed as much effort, took so long or cost so much.This level of activity is justified by our belief that high speedmonolithic amplifiers greatly interest users.

  • Delta Sigma的ADC橋測量技術(shù)

      Sensors for pressure, load, temperature, acceleration andmany other physical quantities often take the form of aWheatstone bridge. These sensors can be extremely linearand stable over time and temperature. However, mostthings in nature are only linear if you don’t bend them toomuch. In the case of a load cell, Hooke’s law states that thestrain in a material is proportional to the applied stress—as long as the stress is nowhere near the material’s yieldpoint (the “point of no return” where the material ispermanently deformed).

  • DN428微型同步升壓轉(zhuǎn)換器

      Alkaline batteries are convenient because they’re easy tofi nd and relatively inexpensive, making them the powersource of choice for portable instruments and devicesused for outdoor recreation. Their long shelf life alsomakes them an excellent choice for emergency equipmentthat may see infrequent use but must be ready to go on amoment’s notice. It is important that the DC/DC convertersin portable devices operate over the widest possiblebattery voltage range to extend battery run time, and thussave the user from frequent battery replacement.

  • TLC2543 中文資料

    TLC2543是TI公司的12位串行模數(shù)轉(zhuǎn)換器,使用開關(guān)電容逐次逼近技術(shù)完成A/D轉(zhuǎn)換過程。由于是串行輸入結(jié)構(gòu),能夠節(jié)省51系列單片機(jī)I/O資源;且價(jià)格適中,分辨率較高,因此在儀器儀表中有較為廣泛的應(yīng)用。 TLC2543的特點(diǎn) (1)12位分辯率A/D轉(zhuǎn)換器; (2)在工作溫度范圍內(nèi)10μs轉(zhuǎn)換時(shí)間; (3)11個(gè)模擬輸入通道; (4)3路內(nèi)置自測試方式; (5)采樣率為66kbps; (6)線性誤差±1LSBmax; (7)有轉(zhuǎn)換結(jié)束輸出EOC; (8)具有單、雙極性輸出; (9)可編程的MSB或LSB前導(dǎo); (10)可編程輸出數(shù)據(jù)長度。 TLC2543的引腳排列及說明    TLC2543有兩種封裝形式:DB、DW或N封裝以及FN封裝,這兩種封裝的引腳排列如圖1,引腳說明見表1 TLC2543電路圖和程序欣賞 #include<reg52.h> #include<intrins.h> #define uchar unsigned char #define uint unsigned int sbit clock=P1^0; sbit d_in=P1^1; sbit d_out=P1^2; sbit _cs=P1^3; uchar a1,b1,c1,d1; float sum,sum1; double  sum_final1; double  sum_final; uchar duan[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f}; uchar wei[]={0xf7,0xfb,0xfd,0xfe};  void delay(unsigned char b)   //50us {           unsigned char a;           for(;b>0;b--)                     for(a=22;a>0;a--); }  void display(uchar a,uchar b,uchar c,uchar d) {    P0=duan[a]|0x80;    P2=wei[0];    delay(5);    P2=0xff;    P0=duan[b];    P2=wei[1];    delay(5);   P2=0xff;   P0=duan[c];   P2=wei[2];   delay(5);   P2=0xff;   P0=duan[d];   P2=wei[3];   delay(5);   P2=0xff;   } uint read(uchar port) {   uchar  i,al=0,ah=0;   unsigned long ad;   clock=0;   _cs=0;   port<<=4;   for(i=0;i<4;i++)  {    d_in=port&0x80;    clock=1;    clock=0;    port<<=1;  }   d_in=0;   for(i=0;i<8;i++)  {    clock=1;    clock=0;  }   _cs=1;   delay(5);   _cs=0;   for(i=0;i<4;i++)  {    clock=1;    ah<<=1;    if(d_out)ah|=0x01;    clock=0; }   for(i=0;i<8;i++)  {    clock=1;    al<<=1;    if(d_out) al|=0x01;    clock=0;  }   _cs=1;   ad=(uint)ah;   ad<<=8;   ad|=al;   return(ad); }  void main()  {   uchar j;   sum=0;sum1=0;   sum_final=0;   sum_final1=0;    while(1)  {              for(j=0;j<128;j++)          {             sum1+=read(1);             display(a1,b1,c1,d1);           }            sum=sum1/128;            sum1=0;            sum_final1=(sum/4095)*5;            sum_final=sum_final1*1000;            a1=(int)sum_final/1000;            b1=(int)sum_final%1000/100;            c1=(int)sum_final%1000%100/10;            d1=(int)sum_final%10;            display(a1,b1,c1,d1);           }         }
