♠ INA190 I-Bidirectional, Amandla aPhantsi, i-Zero-Drift, i-Wide Dynamic Range, i-Precision yangoku-ISense yeAmplufa enoKusebenza
I-INA190 yi-low-power, i-voltage-output, i-currentshunt monitor (ekwabizwa ngokuba yi-amplifier yengqondo yangoku). Esi sixhobo siqhele ukusetyenziselwa ukhuseleko olugqithileyo, umlinganiselo ochanekileyo wangoku wokuphucula isixokelelwano, okanye kwiisekethe zengxelo ezivaliweyo. I-INA190 inokubona ukuhla kwee-shunts kwiindlela zombane eziqhelekileyo ukusuka ku-0.2 V ukuya ku-+40 V, ngokuzimeleyo kumbane wokubonelela.
Igalelo eliphantsi le-bias current yesixhobo livumela ukusetyenziswa kwe-resistors enkulu yangoku, ngaloo ndlela inikezela imilinganiselo yangoku echanekileyo kuluhlu lwe-microamp. I-voltage ephantsi ye-offset ye-architecture ye-zero-drift yandisa uluhlu oluguquguqukayo lomlinganiselo wangoku. Eli nqaku livumela izichasi zengqiqo ezincinci kunye nelahleko yamandla asezantsi, ngelixa zibonelela ngemilinganiselo echanekileyo yangoku.
I-INA190 isebenza ukusuka kwi-1.7-V enye ukuya kwi-5.5-V yobonelelo lwamandla, kwaye izoba ubuninzi be-65 µA yonikezelo lwangoku xa yenziwe; kuphela i-0.1 µA xa ivaliwe. Iinketho ezintlanu zokufumana inzuzo esisigxina ziyafumaneka: 25 V / V, 50 V / V, 100 V / V, 200 V / V, okanye 500 V / V. Isixhobo sichazwe phezu komgangatho wokushisa osebenzayo we -40 ° C ukuya + 125 ° C, kwaye unikezelwa kwi-UQFN, SC70, kunye neephakheji ze-SOT-23.
