♠ Kufotokozera Zamalonda
AD7734 ndi yolondola kwambiri, yakutsogolo yakutsogolo kwa analogi.Kusintha kowona kwa 16-bit pp kumatheka ndi nthawi yonse yotembenuka ya 500 μs (2 kHz kusintha kwa tchanelo), ndikupangitsa kuti ikhale yoyenera pamapulogalamu ochulukitsa ambiri.
Chipangizochi chikhoza kukhazikitsidwa pogwiritsa ntchito mawonekedwe osavuta a digito, omwe amalola ogwiritsa ntchito kuti azitha kugwirizanitsa phokoso lachidziwitso ndi kutulutsa kwa data mpaka 15.4 kHz.
Kutsogolo kwa analogi kumakhala ndi njira zinayi zolowera zokhala ndi malekezero a unipolar kapena 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 akutsogolo a analogi a AD7738 amatha kusinthika panjira zinayi zosiyana kapena zisanu ndi zitatu zolowera mbali imodzi, zimakhala ndi 0.625 V mpaka 2.5 V zolowetsa za bipolar/unipolar, ndipo zimavomereza voliyumu yolowera wamba kuchokera ku 200 mV kupita ku 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
16-bit pp resolution (19 bits ikugwira ntchito) pa 2 kHz
14-bit pp resolution (18 bits ikugwira ntchito) pa 15 kHz
• Pa-chip pa njira ma calibration dongosolo
4 zolowetsa za analogi imodzi
Zolowetsa +5 V, ±5 V, +10 V, ±10 V
Kulekerera kwamphamvu kwambiri
Kufikira ± 16.5 V osakhudza njira yoyandikana nayo
Kufikira ± 50 V mtheradi wokwanira
• 3-waya siriyo mawonekedwe
SPI, QSPI™, MICROWIRE, ndi DSP zimagwirizana
Schmitt amayambitsa zolowetsa za logic
• Ntchito imodzi yokha
5 V kuperekera analogi
3 V kapena 5 V digito kupereka
