Incazelo

I-INA821 iyisikhulisamazwi sokunemba okuphezulu esinikeza amandla aphansi futhi sisebenza ebangeni elibanzi lokuhlinzeka okukodwa noma okukabili.I-resistor yangaphandle eyodwa isetha noma iyiphi inzuzo ukusuka koku-1 kuye ku-10,000.Idivayisi inokunemba okuphezulu ngenxa ye-super-beta transistors, ehlinzeka nge-voltage ye-offset yokufaka ephansi, i-offset voltage drift, i-input bias yamanje, kanye ne-voltage yokufaka nomsindo wamanje.Isekhethi eyengeziwe ivikela okokufaka ekukhuphukeni kwe-overvoltage kufika ku-±40 V.

I-INA821 ilungiselelwe ukunikeza isilinganiso esiphezulu sokunqatshwa kwemodi evamile.Ku-G = 1, isilinganiso sokunqatshwa kwemodi evamile sidlula u-92 dB kubo bonke ububanzi obugcwele bokufakwa kwemodi evamile.Idivayisi yakhelwe ukusebenza kwe-low-voltage kusukela ekunikezeni okukodwa okungu-4.5-V, kanye nezinto ezimbili ezifika ku-±18 V.

I-INA821 itholakala ngamaphakeji angu-8-pin SOIC, VSSOP, kanye ne-WSON, futhi icaciswe ngaphezu kwebanga lokushisa elingu--40°C ukuya ku-+125°C.

1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?

-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.

Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene

Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo

2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?

- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
