♠ Tsanangudzo yeChigadzirwa
Iyo AD7734 ndeyekurongeka kwepamusoro, yakakwira kuburikidza neanalog kumberi kwekupedzisira. Chokwadi 16-bit pp resolution inogoneka neyakakwana yekutendeuka nguva ye500 μs (2 kHz chiteshi switch), ichiita kuti ive yakakodzera kune yakakwirira resolution multiplexing application.
Chishandiso ichi chinogona kugadzirwa kuburikidza neyakapfava yedhijitari interface, iyo inobvumira vashandisi kuti vaenzanise kuita kweruzha vachipesana nedhata yekubuda kusvika ku15.4 kHz.
Iyo analog yekumberi inogumira ine mana-inopera ekuisa nzira ine unipolar kana yechokwadi bipolar yekuisa marenji kusvika ± 10 V uchishanda kubva kune imwe chete +5 V analog supply. Mudziyo uyu une hukuru hwepamusoro uye hwepasi pekutarisa uye unogamuchira analogi yekupinza yakawandisa kusvika ± 16.5 V pasina kusvibisa mashandiro ematanho ari pedyo.
Iyo yekusiyanisa referensi yekuisa maficha "No-Reference" inoona kugona. Iyo ADC inotsigirawo pane imwe chiteshi system calibration sarudzo. Iyo yedhijitari serial interface inogona kugadzirirwa 3-waya kushanda uye inoenderana ne microcontrollers uye dijitari chiratidzo processors. Yese interface yekupinza ndeye Schmitt yakakonzeresa.
Chishandiso ichi chakatsanangurwa kuti chishande pamusoro pe tembiricha yeindasitiri yakawedzerwa kubva -40°C kusvika +105°C.
Mimwe michina mumhuri yeAD7734 ndeye AD7732 uye iyo AD7738.
Iyo AD7732 yakafanana neAD7734, asi iyo analogi yekumberi kumagumo inoratidzira maviri akasiyana akazara ekuisa nzira.
Iyo AD7738 analogi yekumberi inogoneka kune mana akazara mutsauko kana sere imwe-inopera ekuisa nzira, inoratidzira 0.625 V kusvika 2.5 V bipolar / unipolar yekupinza marengesheni, uye inogamuchira yakajairika-modhi yekupinza voltage kubva pa200 mV kuenda kuAVDD - 300mV.
Iyo AD7738 multiplexer inobuda yakadhindwa kunze, ichibvumira mushandisi kuita hurongwa hunogoneka kana chiratidzo chekugadzirisa isati yaiswa kuADC.
