Kufotokozera
INA821 ndi chida chapamwamba chokwera kwambiri chomwe chimagwiritsa ntchito mphamvu zochepa komanso chimagwira ntchito zosiyanasiyana zoperekedwa kamodzi kapena ziwiri.Wotsutsa m'modzi wakunja amakhazikitsa phindu lililonse kuyambira 1 mpaka 10,000.Chipangizocho chili ndi zolondola kwambiri chifukwa cha ma transistors a super-beta, omwe amapereka voteji yotsika kwambiri, kukwera kwamagetsi, kukondera kwapano, ndi magetsi olowera komanso phokoso lapano.Magawo owonjezera amateteza zolowera kuti zisawonjezeke mpaka ± 40 V.
INA821 imakongoletsedwa kuti ipereke chiwongola dzanja chambiri chokana.Pa G = 1, chiŵerengero chokanidwa chofanana chimaposa 92 dB pamtundu wonse wamtundu wamba.Chipangizocho chimapangidwira kuti chizigwira ntchito pang'onopang'ono kuchokera pamtundu umodzi wa 4.5-V, ndi zida ziwiri mpaka ± 18 V.
INA821 imapezeka mu phukusi la 8-pin SOIC, VSSOP, ndi WSON, ndipo imatchulidwa pamwamba pa -40 ° C mpaka +125 ° C kutentha.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
