♠ Sharaxaada Alaabta
AD7734 waa sax heer sare ah, oo wax soo saar sare leh oo analooga ah. Xallinta 16-bit ee saxda ah waa la gaari karaa iyadoo wadarta waqtiga beddelka ee 500 μs (2 kHz kanaalka beddelka), taasoo ka dhigaysa mid ku habboon codsiyada xallinta badan.
Qalabka waxaa lagu habeyn karaa iyada oo loo marayo is-dhexgalka dhijitaalka ah ee fudud, kaas oo u oggolaanaya dadka isticmaala inay isku dheelitiraan waxqabadka buuqa ee ka soo horjeeda xogta soo-saarka ilaa 15.4 kHz.
Dhamaadka hore ee analooga waxa uu leeyahay afar kanaal wax gelin ah oo hal-dhammaad leh oo leh hal-xidhaale ama laba-cirifoodka dhabta ah ee gelinta ilaa ± 10 V marka laga shaqeeyo hal + 5 V analoog ah. Qalabku waxa uu leeyahay awood ogaansho xad dhaaf ah iyo xad-dhaaf ah waxana uu aqbalaa gelinta analogga ah ee ±16.5 V iyada oo aan hoos loo dhigin waxqabadka kanaalada ku xiga.
Gelitaanka tixraaca kala duwan wuxuu leeyahay "Tixraac la'aan" awood lagu ogaado. ADC sidoo kale waxay taageertaa doorashooyinkii habaynta nidaamka kanaalka. Interface-ka taxanaha dhijitaalka ah waxa loo habayn karaa hawl-gal 3-fire ah waxana uu la jaanqaadi karaa kontaroolayaasha yar-yar iyo soo-saareyaasha calaamadaha dhijitaalka ah. Dhammaan wax-soo-saarka interface-ka waxaa kiciyay Schmitt.
Qalabku waxa loo cayimay in uu ku shaqeeyo inta u dhaxaysa heerkulka warshadaha ee fidsan ee -40°C ilaa +105°C.
Qalabka kale ee qoyska AD7734 waa AD7732 iyo AD7738.
AD7732 waxa ay la mid tahay AD7734, laakiin dhamaadkeeda analooga ah waxa uu leeyahay laba kanaal oo si buuxda u kala duwan.
AD7738 dhamaadka hore ee analooga waxaa loo habeyn karaa afar kanaal oo si buuxda u kala duwan ama sideed hal-dhammaadka kanaalada wax gelinta ah, wuxuu leeyahay 0.625 V ilaa 2.5 V laba-cirifoodka / midpolar-ka kala duwanaanshiyaha, wuxuuna aqbalaa korantada gelinta-habka guud ee 200 mV ilaa AVDD - 300mV.
Wax soo saarka Multiplexer AD7738 waxaa lagu dhejiyay dibadda, taasoo u oggolaanaysa isticmaaluhu inuu hirgeliyo faa'iido barnaamij ama qaboojin ka hor inta aan lagu dabaqin ADC.
