♠ Kufotokozera Zamalonda
AD7734 ndi yolondola kwambiri, yakutsogolo yakutsogolo kwa analogi. Kusintha kowona kwa 16-bit pp kumatha kutheka ndi nthawi yonse yotembenuka ya 500 μs (2 kHz tchanelo switching), kupangitsa kuti ikhale yoyenera kugwiritsa ntchito ma multiplexing ambiri.
Chipangizochi chikhoza kukonzedwa pogwiritsa ntchito mawonekedwe osavuta a digito, omwe amalola ogwiritsa ntchito kuti azitha kuwongolera phokoso polimbana ndi kutulutsa kwa data mpaka 15.4 kHz.
Kutsogolo kwa analogi kumakhala ndi njira zinayi zolowera zokhala ndi ma unipolar kapena zowona zenizeni za bipolar mpaka ± 10 V pomwe zikugwira ntchito kuchokera ku + 5 V ya analogi imodzi. Chipangizochi chili ndi mphamvu yodziwira motalikirapo komanso mocheperapo ndipo imavomereza kuwonjezereka kwa analogi ku ± 16.5 V popanda kusokoneza magwiridwe antchito a mayendedwe oyandikana nawo.
Zolemba zosiyanitsa za "No-Reference" zimazindikira kuthekera. ADC imathandiziranso njira zosinthira njira. Mawonekedwe amtundu wa digito amatha kukhazikitsidwa kuti azigwira ntchito pamawaya atatu ndipo amagwirizana ndi ma microcontrollers ndi ma processor a digito. Zolowetsa zonse za mawonekedwe a Schmitt zimayambitsidwa.
Chipangizochi chimatchulidwa kuti chizigwira ntchito pa kutentha kwa mafakitale komwe kumakhala -40 ° C mpaka +105 ° C.
Zida zina mu banja la AD7734 ndi AD7732 ndi AD7738.
AD7732 ndi yofanana ndi AD7734, koma kutsogolo kwake kwa analogi kumakhala ndi njira ziwiri zolowera mosiyanasiyana.
Mapeto a AD7738 analogi amatha kusinthidwa kuti akhale ndi njira zinayi zosiyana kapena zisanu ndi zitatu zokhala ndi mapeto amodzi, zimakhala ndi 0.625 V mpaka 2.5 V bipolar / unipolar input ranges, ndipo amavomereza voliyumu yolowera wamba kuchokera ku 200 mV mpaka AVDD - 300mV.
Zotulutsa za AD7738 multiplexer zimasindikizidwa kunja, zomwe zimalola wogwiritsa ntchito kupeza phindu lokonzekera kapena kukonza ma siginecha asanagwiritsidwe ntchito ku ADC.
• Kusintha kwapamwamba kwa analogi-to-digital (ADC)
24 bits palibe ma code osowa
± 0.0025% kusagwirizana
• Wokometsedwa kuti mofulumira tchanelo kusintha
18-bit pp resolution (21 bits ikugwira ntchito) pa 500 Hz
