♠ LMP91000 Sensor AFE System: AFE Potentiostat La Lahagajin karo ee Codsiyada Dareemida Kiimikada
LMP91000 waa analooga hore ee-dhamaadka (AFE) programmable si loogu isticmaalo codsiyada dareenka korantada ee tamarta-yar. Waxay bixisaa xal dhab ah oo dhamaystiran oo u dhexeeya dareeraha iyo microcontroller kaas oo soo saara korantada wax soo saarka oo u dhiganta unugyada hadda jira. Barnaamijka LMP91000 wuxuu awood u siinayaa inay taageerto dareemayaal badan oo kiimiko ah sida 3-lead sunta gaaska sunta ah iyo 2-lead galvanic unug leh hal naqshad oo ka soo horjeeda xalalka kala duwan. LMP91000 waxay taageertaa dareenka gaaska inta u dhaxaysa 0.5 nA/ppm ilaa 9500 nA/ppm. Waxa kale oo ay ogolaataa beddelka sahlan ee kala duwanaanshaha hadda jira laga bilaabo 5 µA ilaa 750 µA miisaan buuxa.
Eexda unugga la hagaajin karo ee LMP91000 iyo faa'iidada cod-weyneeye (TIA) waa barnaamij lagu samayn karo is-dhexgalka I 2C. Interface-ka I 2C waxa kale oo loo isticmaali karaa ogaanshaha dareemayaasha. Dareemaha heerkulka isku-dhafan waxa uu ku akhriyi karaa isticmaaluhu pinka VOUT waxaana loo isticmaali karaa in lagu bixiyo sixid dheeri ah oo ku jirta µC ama lala socdo si loo xaqiijiyo xaaladaha heerkulka dareeraha.
LMP91000 waxaa loo habeeyay codsiyada quwadda yar-yar wuxuuna ku shaqeeyaa in ka badan 2.7 ilaa 5.25 V. Wadarta isticmaalka hadda wuxuu noqon karaa wax ka yar 10 μA. Badbaadin koronto oo dheeri ah ayaa suurtagal ah iyadoo la damiyo cod-weyneeye TIA oo la gaabiyay korantada tixraaca koronto-shaqeeyaha shaqada leh furaha gudaha.
