Mawu Oyamba
Digital isolator ndi chip mu dongosolo lamagetsi momwe ma digito ndi ma analogi amapatsirana, kuti akhale ndi mawonekedwe apamwamba odzipatula kuti akwaniritse kudzipatula pakati pamagetsi ndi wogwiritsa ntchito.Okonza amayambitsa kudzipatula kuti akwaniritse malamulo a chitetezo kapena kuchepetsa phokoso la pansi.Kudzipatula kwa galvanic kumatsimikizira kuti kutumiza kwa deta sikudutsa kulumikiza magetsi kapena njira zowonongeka, motero kupewa kuopsa kwa chitetezo.Komabe, kudzipatula kumabweretsa malire pa latency, kugwiritsa ntchito mphamvu, mtengo, ndi kukula.Cholinga cha zodzipatula za digito ndikukwaniritsa zofunikira zachitetezo ndikuchepetsa zotsatira zoyipa.

Mafotokozedwe Akatundu
Chizindikiro cholowetsa cha binary chimasinthidwa, kumasuliridwa ku siginecha yokhazikika, kenako kusiyanitsidwa ndi chotchinga chodzipatula cha capacitive.Kudutsa chotchinga chodzipatula, wofananitsa wosiyana amalandira chidziwitso chakusintha kwamalingaliro, kenako ndikukhazikitsa kapena kukonzanso flip-flop ndi gawo lotulutsa molingana.Kuthamanga kwapang'onopang'ono kumatumizidwa kudutsa chotchinga kuti kuwonetsetse kuti mulingo woyenera wa dc wa zotulutsa.Ngati kugunda kwa dc-refresh sikunalandire ma 4 µs aliwonse, zolowetsazo zimaganiziridwa kuti ndizopanda mphamvu kapena sizikuyendetsedwa mwachangu, ndipo dera lolephera kulephera limayendetsa zotulukazo kumtunda wapamwamba.
The capacitance ang'onoang'ono ndi chifukwa nthawi zonse amapereka ntchito mofulumira ndi siginecha mitengo kupezeka kuchokera 0 Mbps (DC) kuti 150 Mbps (Mlingo chizindikiro cha mzere ndi chiwerengero cha voteji kusintha kuti amapangidwa pa sekondi anasonyeza mu mayunitsi bps).Zida za A-option, B-option, ndi C-option zili ndi zolowera za TTL komanso zosefera zaphokoso zomwe zimalepheretsa kuti ma pulse osakhalitsa apitirire kutulutsa kwa chipangizocho.Zida za M-option zili ndi CMOS VCC/2 zolowera ndipo zilibe zosefera zaphokoso komanso kuchedwetsa kufalitsa.
Zida za ISO7220x ndi ISO7221x zimafuna ma voltages awiri a 2.8 V (C-Grade), 3.3 V, 5 V, kapena kuphatikiza kulikonse.Zolowetsa zonse ndizololera 5-V zikaperekedwa kuchokera ku 2.8-V kapena 3.3-V ndipo zotuluka zonse ndi 4-mA CMOS.
Zida za ISO7220x ndi ISO7221x ndizodziwika kuti zimagwira ntchito pa kutentha kwapakati pa -40 ° C mpaka +125 ° C.
