♠ Inkcazo yeMveliso
I-AD7734 ichanekile ephezulu, isiphelo esiphezulu se-analog yangaphambili. Isisombululo esiyinyaniso se-16-bit pp siyafikeleleka ngexesha lokuguqulwa lilonke lama-500 μs (ukutshintsha kwetshaneli 2 kHz), nto leyo eyenza ukuba ifaneleke ngokufanelekileyo kwisisombululo esiphezulu sezicelo zokuphindaphinda.
Isixhobo sinokuqwalaselwa nge-interface yedijithali elula, evumela abasebenzisi ukuba balinganise ukusebenza kwengxolo ngokuchasene nokuhanjiswa kwedatha ukuya kwi-15.4 kHz.
Isiphelo sangaphambili se-analog sinemijelo emine ye-input ene-single ene-unipolar okanye i-bipolar eyinyani yokufakwa kwe-bipolar kwi-± 10 V ngelixa isebenza ukusuka kwi-analog eyodwa + 5 V yokubonelela. Isixhobo sinomgangatho ogqithisileyo kunye nomgangatho ophantsi wokufumanisa kwaye yamkela i-analog input overvoltage kwi-± 16.5 V ngaphandle kokuthobisa ukusebenza kwamajelo akufutshane.
Igalelo lereferensi eyohlukileyo "I-No-Reference" ibona isakhono. I-ADC ikwaxhasa ngeendlela zolungelelwaniso lwenkqubo yejelo ngalinye. I-interface ye-serial ye-digital inokulungiswa kwi-3-wire operation kwaye iyahambelana ne-microcontrollers kunye ne-digital signal processors. Onke amagalelo ojongano aqhutywa yiSchmitt.
Isixhobo sichazwe ukuba sisebenze kuluhlu olwandisiweyo lobushushu bemizi-mveliso ukusuka ku -40°C ukuya +105°C.
Ezinye izixhobo kusapho lwe-AD7734 yi-AD7732 kunye ne-AD7738.
I-AD7732 iyafana ne-AD7734, kodwa isiphelo sayo sangaphambili se-analog sinemijelo emibini eyahluke ngokupheleleyo.
Isiphelo se-analog ye-AD7738 ye-analog front end ilungelelaniswa kwiindlela ezine ezihluke ngokupheleleyo okanye ezisibhozo zokufaka i-single-end, i-0.625 V ukuya kwi-2.5 V ye-bipolar / i-unipolar input ranges, kwaye iyamkela i-voltage yendlela eqhelekileyo ukusuka kwi-200 mV ukuya kwi-AVDD - 300mV.
Imveliso ye-AD7738 ye-multiplexer iphiniweyo ngaphandle, ivumela umsebenzisi ukuba aphumeze inzuzo enokucwangciswa okanye ukulungiswa komqondiso ngaphambi kokuba isetyenziswe kwi-ADC.
