♠ I-LMP91000 Sensor AFE System: I-AFE Potentiostat Elungisekayo Yezinhlelo Zokusebenza Ze-ChemicalSensing Ezinamandla Aphansi
I-LMP91000 iyi-analog front-end ehlelekayo (AFE) ukuze isetshenziswe ezinhlelweni zokuzwa i-electrochemical sensing yamandla amancane.Inikeza isisombululo esiphelele sendlela yesignali phakathi kwenzwa kanye nesilawuli esincane esikhiqiza i-voltage ephumayo ngokulingana nomthamo weseli.Ukuhleleka kwe-LMP91000 kuyenza ikwazi ukusekela izinzwa eziningi ze-electrochemical ezifana nezinzwa zegesi enobuthi eziholayo ezi-3 kanye nezinzwa zamaseli e-galvanic aholayo angu-2 anomklamo owodwa ngokuphambene nezisombululo eziningi ezihlukene.I-LMP91000 isekela ukuzwela kwegesi ebangeni elingu-0.5 nA/ppm kuya ku-9500 nA/ppm.Iphinde ivumele ukuguqulwa okulula kobubanzi bamanje ukusuka ku-5 µA ukuya ku-750 µA esikalini esigcwele.
Inzuzo yeseli elungisekayo ye-LMP91000 kanye nenzuzo ye-transimpedance amplifier (TIA) iyahleleka ngesixhumi esibonakalayo se-I 2C.I-interface ye-I 2C nayo ingasetshenziselwa ukuxilonga izinzwa.Inzwa yezinga lokushisa ehlanganisiwe ingafundwa ngumsebenzisi ngephinikhodi ye-VOUT futhi isetshenziselwe ukunikeza ukulungiswa kwesignali okwengeziwe ku-µC noma igadwe ukuze kuqinisekiswe izimo zezinga lokushisa kusizwa.
I-LMP91000 yenzelwe izinhlelo zokusebenza zamandla amancane futhi isebenza ngaphezu kwebanga lika-voltage elingu-2.7 kuya ku-5.25 V. Isamba esisetshenziswa njengamanje singaba ngaphansi kuka-10 μA.Okunye ukonga amandla kungenzeka ngokucisha isikhulisi se-TIA nokufinyeza i-electrode eyireferensi ku-electrode esebenzayo ngeswishi yangaphakathi.
