LMV324IDR Nyowani yepakutanga chigamba SOP14 Chip 4 chiteshi yakaderera voltage inobuda inoshanda amplifier yakabatanidzwa IC zvikamu.

Zvinoenderana nematanho eakasanganiswa ekushanda amplifiers, anogona kukamurwa muzvikamu zvinotevera.
1, general-chinangwa: iyo general-chinangwa chekushanda amplifier yakagadzirirwa zvinangwa zvakajairika.Chinhu chikuru cherudzi urwu rwechigadzirwa mutengo wakaderera, nhamba huru yezvigadzirwa, uye zviratidzo zvayo zvekushanda zvinogona kukodzera kushandiswa kwese.Muenzaniso μA741 (single op-amp), LM358 (dual op-amp), LM324 (mana op-amps), uye munda-effect chubhu sechikamu chekuisa cheLF356 akadaro.Parizvino ndiwo anonyanya kushandiswa akabatanidzwa anoshanda amplifiers.

2, High Resistance Type
Iyi mhando yeakabatanidzwa mashandiro eamplifier inoratidzwa neakanyanya kusiyanisa modhi yekuisa impedance uye diki diki yekuisa yakarerekera ikozvino, kazhinji inobvisa> 1GΩ ~ 1TΩ, ine IB yemapicoamps mashoma kumakumi emapicoamps.Chiyero chikuru chekuzadzisa izvi zvinangwa kushandisa hunhu hweiyo yepamusoro yekupinza impedance yeFETs kuumba iyo inosiyanisa yekuisa nhanho yeop-amp.Iine FET sedanho rekuisa, kwete chete yakakwira yekupinza impedance, yakaderera yekuisa bias ikozvino, uye zvakanakira zvekumhanya, Broadband, uye yakaderera ruzha, asi yekuisa detuning voltage yakakura.Zvishandiso zvakajairwa zvakabatanidzwa iLF355, LF347 (mana op-amps), uye yepamusoro yekupinza impedance CA3130, CA3140, zvichingodaro.

3, Low-tembiricha kukukurwa mhando
Mune zviridzwa zvakaringana, kuona isina simba chiratidzo, uye zvimwe otomatiki kudzora zviridzwa, zvinogara zvichishuviwa kuti op-amp's detuning voltage inofanira kunge iri diki uye isingashanduke nekupisa.Yakaderera tembiricha inodhiraivha inoshanda amplifiers yakagadzirirwa chinangwa ichi.Iyo OP07, OP27, AD508, uye ICL7650, chopper-yakagadzikana yakadzika-inodhiraivha mudziyo unosanganisira MOSFETs, mamwe epamusoro-chaiyo, yakaderera-kudonha-inodonha mashandiro eamplifiers anoshandiswa zvakajairika nhasi.

4, High-speed mhando
Mukukurumidza A/D uye D/A converters uye vhidhiyo amplifiers, chiyero chekushandura SR cheiyo yakabatanidzwa op-amp inofanira kunge yakakwira uye kubatana-kuwana bandwidth BWG inofanira kunge yakakura zvakakwana senge general-chinangwa chakabatanidzwa op-amps haina kukodzera high-speed applications.High-speed op-amps inonyanya kuratidzwa nepamusoro-soro yekushandura mazinga uye yakafara frequency mhinduro.Common op-amps iLM318, μA715, nezvimwewo, ayo SR=50~70V/us, BWG>20MHz.

5,Low simba rekushandisa mhando.
Seyakanyanya mukana wedunhu remagetsi, kusanganisa kuita maseketi akaomesesa madiki uye akareruka, saka nekuwedzera kwehuwandu hwemashandisirwo ezviridzwa zvinotakurika, zvinofanirwa kushandisa yakaderera magetsi magetsi emagetsi, yakaderera mashandisiro emagetsi ekushandisa amplifier chikamu chinoshanda.Anowanzo shandiswa maamplifiers TL-022C, TL-060C, zvichingodaro, ane simba rekushanda ari ± 2V ~ ± 18V, uye kushandiswa ikozvino 50 ~ 250μA.Zvimwe zvigadzirwa zvasvika pachiyero che μW, semuenzaniso, magetsi eICL7600 ndeye 1.5V, uye kushandiswa kwemagetsi ndeye 10mW, inogona kufambiswa nebhatiri rimwe chete.

6, High voltage uye yakakwirira simba marudzi
Iyo inobuda voltage yeanoshanda amplifiers inonyanya kuganhurirwa nemagetsi.Mune akajairwa mashandiro eamplifiers, iyo yakakwira yekubuda voltage kazhinji ingori makumi mashoma emavolts uye inobuda ikozvino angori mashoma mashoma makumi emamilimita.Kuti uwedzere iyo inobuda voltage kana kuwedzera inobuda ikozvino, iyo yakabatanidzwa op-amp inofanirwa kuwedzeredzwa nekunze nedunhu rekubatsira.Yakakwira voltage uye yakakwira ikozvino yakabatanidzwa op amps inogona kuburitsa yakakwira voltage uye yakakwira ikozvino pasina imwe yekuwedzera dunhu.Semuenzaniso, iyo D41 yakasanganiswa op-amp inogona kupa ma voltages anosvika ± 150V uye iyo μA791 yakasanganiswa op-amp inogona kuendesa inobuda mijenya kusvika ku1A.

7,Programmable control type
Muchiito chekushandisa, pane dambudziko remhando.Kuti uwane yakagadziriswa voltage kubuda, zvinodikanwa kuti uchinje kukwidziridzwa kweiyo inoshanda amplifier.Semuenzaniso, amplifier inoshanda ine magnification kagumi, kana chiratidzo chekuisa chiri 1mv, iyo inobuda voltage iri 10mv, kana magetsi ekuisa ari 0.1mv, inobuda ingori 1mv, kuti uwane 10mv, magnification anofanira kunge ari. yakashandurwa kusvika 100. Semuenzaniso, PGA103A, nekudzora chiyero chepini 1,2 kushandura kuwedzera.
