♠ I-LMP91000 iSensor AFE System: eQinisekayo i-AFE Potentiostat ye-Low-Power Low-PowerSensing Applications
I-LMP91000 yi-programmable analog front-end (AFE) ukuze isetyenziswe kwi-micro-power electrochemical sensing applications.Inika isisombululo esipheleleyo sendlela yomqondiso phakathi kwenzwa kunye ne-microcontroller eyenza i-voltage ephumayo ngokulinganayo kwiseli yangoku.Ukucwangciswa kwe-LMP91000 kwenza ukuba ikwazi ukuxhasa izinzwa ezininzi ze-electrochemical ezifana ne-3-lead yegesi eyityhefu kunye ne-2-lead galvanic cell sensors kunye noyilo olunye ngokuchasene nezisombululo ezininzi.I-LMP91000 ixhasa uvakalelo lwegesi kuluhlu lwe-0.5 nA/ppm ukuya kwi-9500 nA/ppm.Ikwavumela uguqulo olulula loluhlu lwangoku ukusuka kwi-5 µA ukuya kwi-750 µA isikali esipheleleyo.
I-LMP91000's i-adjustable cell bias kunye ne-transimpedance amplifier (TIA) inzuzo iyacwangciswa nge-interface ye-I 2C.I-interface ye-I 2C ingasetyenziselwa ukuxilongwa kwenzwa.Isivamvo sobushushu esihlanganisiweyo sinokufundwa ngumsebenzisi nge-PIN ye-VOUT kwaye isetyenziselwa ukunika ulungiso lophawu olongezelelweyo kwi-µC okanye ibekwe esweni ukuqinisekisa iimeko zobushushu kwisixhobo soluvo.
I-LMP91000 ilungiselelwe usetyenziso lwamandla amancinci kwaye isebenze ngaphaya koluhlu lwe-voltage ye-2.7 ukuya kwi-5.25 V. Ukusetyenziswa kwangoku okupheleleyo kunokuba ngaphantsi kwe-10 μA.Ukonga okongeziweyo kwamandla kunokwenzeka ngokucima iamplifier ye-TIA kunye nokunciphisa i-electrode yereferensi kwi-electrode esebenzayo kunye nokutshintsha kwangaphakathi.
