Description Ibisobanuro
AD7734 nibisobanuro bihanitse, byinjira cyane bigereranya imbere.Nukuri 16-bit pp ikemurwa irashobora kugerwaho hamwe nigihe cyo guhindura cya 500 μs (2 kHz umuyoboro uhindura), bigatuma bikwiranye nibyiza byo gukemura byinshi.
Igikoresho kirashobora gushyirwaho hifashishijwe interineti yoroshye ya digitale, ituma abayikoresha baringaniza imikorere y urusaku rwinjiza amakuru agera kuri 15.4 kHz.
Impera yimbere igereranya imiyoboro ine yinjiza imwe hamwe na bipolar yukuri cyangwa bipolar yukuri igera kuri ± 10 V mugihe ikorera kumurongo umwe +5 V.Igikoresho gifite ubushobozi burenze urugero kandi butagaragaza ubushobozi bwo gutahura kandi bwemera kwinjiza ibintu birenze urugero kuri .5 16.5 V bitatesheje agaciro imikorere yimiyoboro yegeranye.
Itandukaniro ritandukanye ryinjiza ibiranga "Oya-Reba" ubushobozi bwo kumenya.ADC nayo ishyigikira inzira ya sisitemu yo guhitamo.Imigaragarire ya sisitemu irashobora gushyirwaho kugirango ikore 3-wire kandi irahujwe na microcontrollers hamwe na sisitemu yo gutangiza ibimenyetso.Imigaragarire yose yinjiza ni Schmitt yatewe.
Igikoresho cyagenwe kugirango gikore hejuru yubushyuhe bwagutse bwinganda zingana na 40 ° C kugeza kuri + 105 ° C.
Ibindi bikoresho mumuryango wa AD7734 ni AD7732 na AD7738.
AD7732 isa na AD7734, ariko igereranya ryayo imbere iranga imiyoboro ibiri itandukanye rwose.
Imbere ya AD7738 igereranya imbere irashobora kugereranywa kumirongo ine itandukanye cyangwa umunani imwe yinjiza imwe, iranga 0.625 V kugeza kuri 2.5 V bipolar / unipolar yinjiza, kandi ikemera uburyo busanzwe bwo kwinjiza amashanyarazi kuva mV 200 kugeza AVDD - 300mV.
AD7738 multiplexer isohoka hanze, yemerera uyikoresha gushyira mubikorwa inyungu zishobora gutangwa cyangwa ibimenyetso byerekana mbere yo gukoreshwa kuri ADC.
