I-LMV797MMX/NOPB (Entsha&Eyoqobo Isitoko)I-Crcuit Chips Ehlanganisiwe ye-IC Electronics Umhlinzeki Othembekile

incazelo emfushane:

Umndeni we-LMV93x-N (LMV931-N single, LMV932-N dual kanye ne-LMV934-N quad) zingama-amplifiers anamandla aphansi, aphansi.Umndeni we-LMV93x-N usebenza kusukela ku-1.8-V kuya ku-5.5-V wokuhlinzeka ngogesi futhi unokufaka nokukhiphayo ukusuka kumzila wesitimela ukuya kusitimela.I-voltage yemodi evamile yokufaka inweba ku-200 mV ngaphezu kwalokho okunikezwayo okwenza umsebenzi othuthukisiwe usebenze ngaphezu kobubanzi bevolthi yokunikezela.Okukhiphayo kungashwibilika ujantshi uye kusitimela ungalayishiwe futhi ku-105 mV ukusuka ujantshi nomthwalo ongu-600-Ω ekunikezeni okungu-1.8-V.Amadivayisi e-LMV93x-N alungiselelwe ukusebenza ku-1.8 V, okuwenza alungele amaseli amabili aphathwayo, amasistimu asebenza ngebhethri kanye nesistimu ye-Li-Ion yeseli elilodwa.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amadivayisi e-LMV93x-N abonisa isilinganiso esihle kakhulu samandla wejubane, afinyelela umkhiqizo womkhawulokudonsa ongu-1.4-MHz ku-voltage yokunikezela engu-1.8-V enamanje okunikezwayo okuphansi kakhulu.Amadivayisi e-LMV93x-N angakwazi ukushayela umthwalo ongu-600-Ω kanye nomthwalo we-capacitive ofika ku-1000-pF ngokukhala okuncane.
Lezi zixhobo nazo zinenzuzo ephezulu ye-DC engu-101 dB, okuyenza ifanelekele izinhlelo zokusebenza ze-low-frequency.I-LMV93x-N eyodwa inikezwa ekulondolozeni isikhala 5-pin SC70 kanye namaphakheji we-SOT-23.I-LMV932-N ekabili iku-8-pin VSSOP kanye namaphakheji e-SOIC kanti i-quad LMV934-N iku-14-pin TSSOP kanye ne-SOIC
amaphakheji.Lawa maphakheji amancane ayizixazululo ezifanelekile zamabhodi e-PC avinjelwe endaweni kanye nezinto zikagesi eziphathwayo ezifana nomakhalekhukhwini namathebulethi.

Ukukhetha kanye Nesicelo

Ukukhetha nokusebenzisa ama-amplifiers.
Kunezigaba eziningi nezinhlobonhlobo zama-amplifiers okusebenza ahlanganisiwe, okufanele akhethwe ngokunengqondo futhi asetshenziswe ngokuhambisana nezidingo zangempela zokusetshenziswa.
(1) Zama ukusebenzisa ama-amplifiers okusebenza ahlanganisiwe anenhloso ejwayelekile.Uma uhlelo lusebenzisa ama-amplifiers amaningi okusebenza, ngangokunokwenzeka ukusebenzisa amasekethe amaningi ahlanganisiwe we-amplifier wokusebenza, njenge-LM324, LF347, njll. kukhona ama-amplifiers amane asebenzayo ahlanganiswe ndawonye kusekethe ehlanganisiwe.
(2) Ukukhethwa kwangempela kwe-amplifier yokusebenza edidiyelwe, kodwa futhi cabangela uhlobo lomthombo wesignali (umthombo wamandla kagesi noma umthombo wamanje), uhlobo lomthwalo, amandla kagesi okukhipha isikhulisi esisebenzayo ahlanganisiwe kanye namanje ukuze kuhlangatshezwane nezidingo, indawo ezungezile. izimo, i-amplifier yokusebenza edidiyelwe evunyelwe ukusebenza ibanga, ububanzi bamandla kagesi okusebenza, ukusetshenziswa kwamandla nevolumu nezinye izici ukuhlangabezana nezidingo.Isibonelo, ekukhuliseni amasiginali we-AC njengomsindo nevidiyo, kufanelekile kakhulu ukukhetha i-amplifier esebenzayo enezinga elikhulu lokuguqulwa;ukuze kucutshungulwe amasiginali e-DC abuthakathaka, kufaneleka kakhulu ukukhetha i-amplifier esebenza ngokunemba okuphezulu (okungukuthi, i-detuning current, i-detuning voltage, kanye ne-temperature drift kuncane kakhulu).
(3) Ngaphambi kokusetshenziswa, kuyadingeka ukuqonda izigaba kanye nemingcele kagesi yama-amplifiers ahlanganisiwe okusebenza, nokucacisa ifomu lephakheji, ukuhlelwa komthofu wangaphandle, izintambo zephini, ububanzi bamandla kagesi, njll.
(4) Inethiwekhi yokususa ukudlidliza kufanele ixhunywe njengoba kudingekile, kucatshangelwa umkhawulokudonsa osezandleni zokukwazi ukususa ukudlidliza.
(5) I-amplifier edidiyelwe yokusebenza iwumgogodla wesekethe ye-elekthronikhi, ukuze kuncishiswe umonakalo, kufanele kuthathwe izinyathelo zokuvikela ezifanele.

Izinkomba Nemihlahlandlela

Izinkomba zokukhetha i-amplifier yokusebenza kanye nemihlahlandlela yokuklama isicelo
Ngokuvamile, ama-amplifiers okusebenza okujwayelekile kufanele asetshenziswe ngangokunokwenzeka, ngoba kulula ukuyithola futhi angabizi, kuphela lapho uhlobo lwenhloso evamile lungakwazi ukuhlangabezana nezidingo, lungasebenzisa uhlobo olukhethekile, olunganciphisa izindleko, kodwa futhi kulula ukuqinisekisa ukutholakala.
Ngokuthuthuka kobuchwepheshe obuvuthiwe, ukusetshenziswa kwama-amplifiers okusebenza kuya ngokuya kusakazeka, futhi lapho kubhekene nezinhlobo ezahlukahlukene zama-amplifiers okusebenza, kunemiyalo ejwayelekile yezobuchwepheshe yokukhetha kwabo.Lokhu okokukhetha ukuhlangabezana nezidingo, kodwa futhi ukulondoloza imithombo yedatha kudlale indima enkulu.Izinkomba zokukhetha ezivame ukusetshenziswa yilezi:
Isinyathelo sokuqala ukukhetha i-voltage.Njengoba ama-amplifiers amaningi akhiqizwe izinhlelo zokusebenza zezimboni engu-±15V, kodwa uma kucatshangelwa ukuthi azothuthukiswa kumadivayisi aphathwayo asebenza ku-3V (noma ngaphansi kuka-5V), lolu chungechunge lwe-±15V lungafakwa.Ngaphezu kwalokho, isinqumo sokuthi iyiphi iphakheji kanye nentengo okufanele isekelwe ezidingweni.
Ukunemba Okuhlobene Ikakhulukazi nokuhluka kwe-voltage yokususa okokufaka (i-Vos) kanye nokwehla kwezinga lokushisa okuhlobene kanye ne-PSRR ne-CMRR.
I-Gain Bandwidth Product (GBW) Umkhawulokudonsa wokuzuza wohlobo lwempendulo kagesi ithola i-op-amp inquma umkhawulokudonsa owusizo kuhlelo lokusebenza olunikeziwe.
Ukusetshenziswa kwamandla (imfuneko ye-LQ) Indaba ebalulekile ezinhlelweni eziningi.Njengoba ama-amplifiers asebenzayo enamandla okuba nomthelela omkhulu ekusabalaliseni amandla esistimu yonke, i-quiescent current iwukucatshangelwa kwedizayini ebalulekile, ikakhulukazi ezinhlelweni ezisebenza ngamandla ebhethri.
I-Input bias current (LB) ingathonywa umthombo noma ukuthikamezeka kwempendulo futhi kungaholela ekukhishweni kwamaphutha.Izinhlelo zokusebenza ezinokuvinjelwa komthombo ophezulu noma izici zempendulo ze-impedance ephezulu (njenge-transimpedance amplifiers noma izihlanganisi) ngokuvamile zidinga imisinga yokuchema okokufaka okuphansi;Okokufaka kwe-FET kanye ne-CMOS op amps ngokuvamile kunikeza ama-currents okokufaka aphansi kakhulu.
Usayizi wephakheji uncike kuhlelo lokusebenza futhi i-op-amp ikhethwa ukuze ihambisane nezidingo zephakheji.

Izinzuzo

Izinzuzo zenhloso evamile ye-op amps
Izinzuzo eziyinhloko yintengo ephansi, ukucaciswa okulinganiselwe kanye nohlu olubanzi lwezinketho zomkhiqizo.

Izinhlelo zokusebenza

Izicelo zenhloso ejwayelekile ye-op amps
Ngenxa yezici zabo, zisetshenziswa ezinhlobonhlobo zezicelo.Izinhlelo zokusebenza eziyinhloko yilapho izidingo zobuchwepheshe zilinganiselwe.Ukuze kuhlangatshezwane nezidingo zomsebenzi, kunqoba umnotho kanye nokusebenza.Inhloso evamile ehlanganisiwe ye-op amps ifanele ukukhulisa amasiginali aphansi.
