Chotsatiracho chimadalira kusintha kwa katswiri wa 20k.

LM358 ndi LM358P ndi mtundu womwewo wa tchipisi a Treptifari, ndipo kusiyana kwawo kumakhala mu fomu.LM358P imagwiritsa ntchito dips (phukusi lapamwamba), lomwe limakhala labwino kwambiri kukhazikitsa mayeso;Pomwe LM358 imagwiritsa ntchito soic (phukusi laling'ono lazigawo lophatikizira), lomwe ndi loyenera kupanga zokha.Ngakhale mafomu a phukusi ndi osiyana, magawo awiriwo ali ofanana, monga magetsi osokoneza bongo a magetsi, ndikupeza mankhwala a bandwidth.

Tiyenera kudziwa kuti pakhoza kukhala kusiyana pang'ono pakati pa LM358 ndi LM358P yopangidwa ndi opanga osiyanasiyana.Chifukwa chake, muzothandiza, tiyenera kusankha mtundu woyenera komanso wopanga malinga ndi zosowa zina.Nthawi zambiri, LM358 ndi LM358P ndi mitundu yosiyanasiyana ya phukusi lomweli.Ali ndi magawo omwewo amagetsi ndi ntchito, kotero angagwiritsidwe ntchito mosiyanasiyana.Pakati pawo, LM358P amatenga phukusi la anti-Static, lomwe ndi loyenera kugwiritsa ntchito m'malo ovuta.Komabe, nthawi zambiri, mitundu iwiriyi imasinthika.Pofuna kuonetsetsa kukhazikika komanso magwiridwe ake, tikulimbikitsidwa kuti mupeze pepala loyenererana musanagwiritse ntchito kuti zitsimikizire ngati magawo ake ndi phukusi lake ndi loyenera kugwiritsa ntchito pulogalamuyi.

Mukamagwiritsa ntchito LM358P, tifunika kuganizira mbali zotsatirazi.

Tiyenera kuwonetsetsa kuti kuchuluka kwa zomwe zikulowetsa ndi zizindikiro zotuluka zimagwirizana ndi kutulutsa kwa LM358P.Ngati chizindikiro cholowera chatuluka mu LM358PS pamlingo wa LM3588, chimasokoneza kapena kuwononga chipangizocho.

Mukamalumikiza LM358P, choyamba tiyenera kufotokozera bwino za pini iliyonse tisanawonetsetse kuti ali ndi vuto.Mwachitsanzo, zikhomo zolowa zimayenera kulumikizidwa ndi siginito kuti mulandire chizindikiro, pomwe zikhomo zotuluka zimayenera kulumikizidwa ndi katundu kuti zithetse chizindikiro.Zikhomo zamphamvu zimayenera kulumikizidwa ndi gwero lokhazikika, pomwe zikhomo zam'mphepete zimafunikira kuti zitsimikizike kuti zitsimikizire mphamvu zoyenera kudera.Nthawi yomweyo, tiyenera kumvetsera mwa njira yolumikizirana ndi zikhomo, kuti tisapangitse kulephera kwa madera chifukwa cholakwa.

Ufulu wowononga ungayambitse magwiridwe antchito a LM358P kuti athe kuwonongeka, kapena ngakhale kuwononga mopitirira muyeso.Chifukwa chake, tifunika kuganizira bwino vuto losinthanitsa popanga dera.Njira yodziwika bwino yotentha ndikuwonjezera kutentha kwa ogwirira ntchito kuti muwonjezere malo ochitira kutentha ndikuwongolera mphamvu yotentha yotentha.

Pazolinga zina, kubwezeretsa pafupipafupi kungafunikire kuonetsetsa kukhazikika kwa LM358P.Pochita izi, choyamba tiyenera kudziwa kuchuluka kwa kubweza komwe kumafunikira malinga ndi zofunika kugwiritsa ntchito, kenako sankhani mtengo woyenera.Kenako, timalumikiza termitor ya capical to pini yolipiritsa ya LM358P ndikugwedeza.Mwanjira imeneyi, Caakototor amatha kupanga network network ndi otsimikiza mkati mwa omwe amapepuka, akukwaniritsa motero.

Kuti muwonetsetse ntchito yokhazikika ya LM358P yomwe imagwira ntchito ya LM358P yogwira ntchito, tiyenera kuganizira kuti tiyenera kuteteza chipilala cha magetsi, kupitilirapo, komanso zinthu zina zosafunikira.Makamaka, titha kukwanitsa kutetezedwa mokwanira motsutsana ndi zopitilira muyeso powonjezera mndandanda wokakamira kapena kugwiritsa ntchito chipangizo chotetezera choteteza.Pakadali pano, kuti tigwiritse ntchito zamakono, titha kugwiritsa ntchito zida monga ma saiters kapena mafose kuti muwonetsetse kuti kutuluka kwaposachedwa.

Chonde onetsetsani kuti mwapereka vol voltoge yoyenera ya LM358P.LM358P imatha kugwira ntchito munjira zonse zoperekera magwiritsidwe apadera komanso zowonjezera, kutengera zomwe tikugwiritsa ntchito.Ngati tisankha kugwiritsa ntchito magetsi amodzi, ndiye kuti chonde onetsetsani kuti magetsi amapereka sikuti ndi otsika kuposa magetsi ochepa ofunikira ndi LM358P.Ngati tisankha kugwiritsa ntchito magetsi awiri, ndiye kuti tiyenera kupereka zivundikiro zabwino komanso zoyipa.

Mukapanga bolodi, tiyenera kuonetsetsa kuti pali kulumikizana kwabwino pakati pa chizindikiro cha chizindikiro ndi mphamvu kuti tichepetse phokoso komanso kusokoneza.Titayika board, tiyenera kusunga chikwangwani choyandikira pafupi ndi mphamvu ndikuyesera kupewa zikwangwani zowoloka nthaka.Kuphatikiza apo, kugwiritsa ntchito njira yotsika yapansi kumachepetsa kukana ndi kusanja kwa waya wapansi, komwe kumachepetsa phokoso.Pakadali pano, pofuna kutsimikizika kukhazikika kwa magetsi ndikuchepetsa phokoso lamphamvu, tiyenera kugwiritsa ntchito thicker kapena waya wamphamvu kuti tilumikizane ndi kuchuluka kwa magetsi kuti tichepetse mizere ya magetsi.

LM358 ili ndi mapulogalamu angapo, kuphatikiza masitepe a Ap-AP-AMMS, DY

Malinga ndi mtundu wa National Semiconduct Corration's pr ndi n ndi fomu ya chipangizocho.Phukusi la LM368N ndi phukusi la pulasitiki lapamwamba.LM358P iyenera kukhala phukusi limodzi.

Kusiyana pakati pa LM358 & LM741 ndi, LM358 ndi yatsopano ndipo ili ndi AP-Amp Amp pa 741 OP-Amp okha ndi omwe.Onse awiri ali ndi zikhomo 8.

Ili ndi ma amps awiri odziyimira pawokha ndi magetsi amodzi mu phukusi limodzi.IC ingathenso kugwira ntchito kuchokera ku magetsi ogawanika ndi kukula kwa magetsi sikukhudza mphamvu yotsika yomwe imatulutsa.
