TLC2272ACDR Yongerera imbaraga - Op Amps Dual R / R Op Amp

TLC2272 na TLC2274 nibintu bibiri kandi bine byongera imbaraga ziva muri Texas Instruments. Ibikoresho byombi byerekana gari ya moshi-kuri-gari ya moshi isohoka kugirango yongere imbaraga zingana murwego rumwe cyangwa kugabana-gutanga. Umuryango wa TLC227x utanga 2 MHz yumurongo wa 3 na V / μs yikigereranyo cyibisabwa byihuse. Ibi bikoresho bitanga imikorere igereranijwe ya AC mugihe ifite urusaku rwiza, kwinjiza offset ya voltage, hamwe no gukwirakwiza ingufu kurenza CMOS ikora. TLC227x ifite urusaku rwurusaku rwa 9 nV / √Hz, munsi yikubye kabiri ibisubizo byapiganwa.

Umuryango wa TLC227x wibikoresho, werekana impedance nyinshi yinjira hamwe n urusaku ruke, nibyiza kubimenyetso bito bito byerekana ibintu byihuta cyane nka transducers ya piezoelectric. Kubera urwego rwo gukwirakwiza ingufu za micropower, ibyo bikoresho bikora neza mugukurikirana intoki no kugenzura kure. Mubyongeyeho, ibyasohotse muri gari ya moshi-kuri-gari ya moshi, hamwe nibikoresho bimwe cyangwa bigabanijwe, bituma uyu muryango uhitamo neza mugihe uhuza na analog-to-digitale (ADCs). Kubisabwa neza, umuryango wa TLC227xA urahari hamwe ninjiza ntarengwa ya offset ya voltage ya 950 μV. Uyu muryango urangwa neza kuri 5 V na ± 5 V.

TLC227x nayo ikora cyane cyane kuri TLC27x mubishushanyo bisanzwe. Zitanga umusaruro wiyongereye urwego, urusaku rwo hasi rwumuvuduko, hamwe na voltage yo hasi ya offset. Iyi mikorere yongerewe imbaraga ibemerera gukoreshwa murwego rwagutse rwa porogaramu. Kuri porogaramu zisaba gusohora cyane kandi nini ya voltage yagutse, reba ibikoresho bya TLV2432 na TLV2442.

Niba igishushanyo gisaba amplifier imwe, reba umuryango wa TLV2211, TLV2221 na TLV2231. Ibi bikoresho ni ibyuma bya gari ya moshi byongera imbaraga muri pake ya SOT-23. Ingano ntoya hamwe no gukoresha ingufu nkeya bituma biba byiza cyane, ibikoresho bikoreshwa na bateri.
