ʻO ka INA821 kahi mea hoʻonui kiʻekiʻe kiʻekiʻe e hāʻawi ana i ka hoʻohana haʻahaʻa haʻahaʻa a e hana ana ma luna o kahi ākea ākea hoʻokahi a i ʻole pālua.Hoʻonohonoho ka resistor waho hoʻokahi i ka loaʻa mai 1 a 10,000.Loaʻa ka pololei o ka hāmeʻa ma muli o nā transistors hoʻokomo super-beta, e hāʻawi ana i ka uila offset haʻahaʻa haʻahaʻa, offset voltage drift, input bias current, a me ka voltage input a me ka walaʻau o kēia manawa.Mālama ka circuitry hou i nā mea hoʻokomo mai ka overvoltage a hiki i ± 40 V.
Hoʻolālā ʻia ka INA821 e hāʻawi i kahi ratio hōʻole maʻamau maʻamau.Ma G = 1, ʻoi aku ka lakio hōʻole ʻana i ke ʻano maʻamau ma mua o 92 dB ma waena o ka pae hoʻokomo piha.Hoʻolālā ʻia ka hāmeʻa no ka hana haʻahaʻa haʻahaʻa mai kahi lako hoʻokahi 4.5-V, a me nā lako ʻelua a hiki i ±18 V.
Loaʻa ka INA821 i nā pūʻolo 8-pin SOIC, VSSOP, a me WSON, a ua kuhikuhi ʻia ma luna o ka pae wela -40°C a +125°C.
1. ʻO wai nā limahana ma kāu ʻoihana R & D?He aha kāu mau ʻike?
- Luna Hoʻokele R & D: hoʻolālā i ka hoʻolālā R & D lōʻihi o ka hui a hopu i ke kuhikuhi o ka noiʻi a me ka hoʻomohala ʻana;Alakaʻi a mālama i ka ʻoihana r&d e hoʻokō i ka hoʻolālā r&d ʻoihana a me ka hoʻolālā R&D makahiki;E kāohi i ka holomua o ka hoʻomohala ʻana i nā huahana a hoʻoponopono i ka hoʻolālā;E hoʻonohonoho i ka hui noiʻi a me ka hoʻomohala huahana maikaʻi loa, ka loiloi a me ke aʻo ʻana i nā limahana ʻenehana pili.
Luna R&D: hana i ka hoʻolālā R&D huahana hou a hōʻike i ka hiki o ka hoʻolālā;Mālama a mālama i ka holomua a me ka maikaʻi o ka hana r&d;E noiʻi i ka hoʻomohala huahana hou a hāʻawi i nā hopena kūpono e like me nā koi o ka mea kūʻai aku ma nā kahua like ʻole
Nā limahana R&d: hōʻiliʻili a wehe i nā ʻikepili koʻikoʻi;polokalamu kamepiula;Ke hana nei i nā hoʻokolohua, nā hoʻokolohua a me nā loiloi;E hoʻomākaukau i nā mea hana a me nā mea hana no nā hoʻokolohua, nā hoʻokolohua a me nā loiloi;E hoʻopaʻa i ka ʻikepili ana, e helu a hoʻomākaukau i nā pakuhi;Hana i nā noiʻi helu
2. He aha kāu noiʻi huahana a manaʻo hoʻomohala?
- ʻO ka manaʻo o ka huahana a me ke koho ʻana i ka manaʻo huahana a me ka loiloi wehewehe huahana a me ka hoʻolālā papahana papahana a me ka hoʻomohala ʻana i ka huahana hoʻāʻo a me ka hoʻomaka ʻana i ka mākeke
