ROHM LMR1001YF-C Voltage Rail-to-Rail Input uye Output CMOS Amplifier
Mashoko Akakosha
Seketi iyi inoteedzera mhinduro yechinguvana kune sine wave kuisa nevoltage muteveri akagadziriswa Op-Amps. Unogona kuona kubuda kwevoltage uye nekutendeseka kwakaita sine wave input voltage inoburitswa. Iwe unogona kugadzirisa maparamendi ezvikamu zvinoratidzwa mubhuruu, seVSOURCE, kana peripheral components, uye kutevedzera vol.tage muteveri ane chinodiwa chekushanda mamiriro.
Iwe unogona kutevedzera dunhu mune yakaburitswa application note: Operational ampLifier, Muenzanisi (Tutorial). [JP] [EN] [CN] [KR]
General Cautions
Kuchenjerera 1: Hukoshi kubva pamibairo yekufananidza haina kuvimbiswa. Ndapota shandisa mhinduro idzi segwara rekugadzira kwako.
Kuchenjerera 2: Aya mamodhi maitiro akanyatso kuTa=25°C. Saka, mugumisiro wekufananidza nekusiyana kwekushisa kunogona kusiyana zvakanyanya kubva kune mhedzisiro neiyo yakaitwa pabhodhi rekushandisa chairo (chiyero chaicho).
Kuchenjerera 3: Ndokumbira utarise kune Chinyorwa chekushandisa cheOp-Amps yeruzivo rwehunyanzvi ruzivo.
Kuchenjerera 4: Hunhu hunogona kuchinja zvichienderana nechaiyo bhodhi dhizaini uye ROHM inokurudzira zvakasimba kuti utarise kaviri iyo hunhu nebhodhi chaiyo apo machipisi achaiswa pairi.

Cherechedzai
- Ruzivo rwuri mugwaro iri rwakaitirwa kuunza ROHM Group (inozonzi ROHM) zvigadzirwa. Paunenge uchishandisa ROHM zvigadzirwa, ndapota simbisa izvo zvichangoburwa zvakatemwa kana madhetidheti usati washandisa.
- Zvigadzirwa zveROHM zvakagadzirirwa uye kugadzirwa kuti zvishandiswe mune zvakajairika zvemagetsi zvishandiso uye mashandisirwo (seAudio Visual midziyo, Hofisi Automation midziyo, nharembozha midziyo, midziyo yemumba, midziyo yekuvaraidza, nezvimwewo) kana yakatsanangurwa mumadhetabheti. Naizvozvo, ndapota taura nemumiriri wekutengesa ROHM usati washandisa zvigadzirwa zveROHM mumidziyo kana michina inoda kuvimbika kwakanyanya uye kutadza kwayo kana kusashanda kunogona kukonzera njodzi kana kukuvara kuhupenyu hwevanhu kana muviri kana kumwe kukuvadzwa kwakanyanya (senge midziyo yekurapa, chekufambisa, traffic, ndege. , zvitundumuseremusere, zvidzori zvemagetsi enyukireya, kudzora mafuta, midziyo yemotokari zvinosanganisira zvinhu zvemotokari, nezvimwewo zvinozonzi Specific Applications). Kunze kwekunge kwabvumiranwa neimwe nzira nekunyora neROHM pachine nguva, ROHM haizove nemutoro kana mhosva yekukuvadza, mari, kana kurasikirwa kwaunoitwa newe kana mapato echitatu kubva mukushandiswa kweROHM Zvigadzirwa zveMashandisirwo Akanyanya.
- Zvigadzirwa zvemagetsi, kusanganisira semiconductors, zvinogona kukundikana kana kusashanda pane imwe chiyero. Ndokumbira uve nechokwadi chekushandisa, pamabasa ako pachako, akakwana ekuchengetedza matanho anosanganisira asi asina kuganhurirwa kukundikana-yakachengeteka dhizaini kurwisa kukuvara kwemuviri, uye kukuvadza kune chero pfuma, iyo kutadza kana kusashanda zvakanaka kwezvigadzirwa kungakonzeresa.
- Ruzivo rwuri mugwaro iri, kusanganisira application wedunhu examples uye zvimiro zvadzo, zvakagadzirirwa kutsanangura chiyero chekushanda uye kushandiswa kweROHM zvigadzirwa, uye hazvina kuitirwa kuvimbisa, zviri pachena kana zvisina kujeka, kushanda kwechigadzirwa mumichina chaiyo ichashandiswa. Nekuda kweizvozvo, iwe ndiwe wega unozvidavirira pazviri, uye iwe unofanirwa kushandisa yako yakazvimirira yekusimbisa uye kutonga mukushandiswa kweruzivo rwakadaro rwuri mugwaro iri. ROHM haizove nemutoro nenzira ipi neipi kana kuve nemhosva yekukuvadza, mari, kana kurasikirwa kunoitwa newe kana mapato echitatu kubva mukushandiswa kweruzivo rwakadaro.
- Paunenge uchiendesa kunze zvigadzirwa zveROHM kana matekinoroji anotsanangurwa mugwaro rino kune dzimwe nyika, unofanirwa kutevedzera maitiro uye zvisungo zvinotemerwa mumitemo yese inotengeswa kunze kwenyika, senge Foreign Exchange uye Foreign Trade Act uye US Export Administration Regulations, uye wotevera nzira dzinodiwa maererano nezviga izvi.
- Iwo ruzivo rwehunyanzvi uye data rinotsanangurwa mugwaro rino, kusanganisira rakajairwa maseketi ekushandisa, ndeekareampizvo chete uye hazvina kuitirwa kuvimbisa kusununguka kubva mukutyorwa kwevechitatu mapato euchenjeri pfuma kana dzimwe kodzero. ROHM haipe chero rezenisi, kutaura kana kutaura, kushandisa, kushandisa, kana kushandisa chero pfuma yeruzivo kana dzimwe kodzero dzine kana kudzorwa neROHM kana chero mapato echitatu maererano neruzivo rwurimo.
- Hapana chikamu chegwaro iri chinogona kudhindwa patsva kana kudhindwa zvakare mune chero nzira neimwe nzira pasina chibvumirano chakanyorwa cheROHM.
- Ruzivo rwese rwuri mugwaro iri nderwezvino kubva pazuva rekuburitswa uye rinogona kuchinja pasina chiziviso. Usati watenga kana kushandisa ROHM zvigadzirwa, ndapota simbisa ruzivo rwazvino nemumiriri wekutengesa ROHM.
- ROHM haibvumire kuti ruzivo rwuri pano haruna kukanganisa. ROHM haizove nemutoro nenzira ipi zvayo kana mhosva yekukuvadza, mari, kana kurasikirwa kunoitwa newe kana mapato echitatu zvichikonzerwa nekukanganisa kuri mugwaro iri.
