♠ LMP91000 Sensor AFE System: Configurable AFE Potentiostat ya Low-Power ChemicalSensing Application
LMP91000 ndi pulogalamu yokhazikika ya analog kutsogolo (AFE) kuti igwiritsidwe ntchito pamagetsi amagetsi amagetsi ang'onoang'ono. Imapereka njira yothetsera njira yathunthu pakati pa sensa ndi microcontroller yomwe imapanga mphamvu yamagetsi yofanana ndi selo yamakono. Kukonzekera kwa LMP91000 kumatheketsa kuthandizira masensa angapo a electrochemical monga masensa atatu otsogolera mpweya wapoizoni ndi ma 2-lead galvanic cell sensors okhala ndi kapangidwe kamodzi kosiyana ndi mayankho angapo. LMP91000 imathandizira kukhudzidwa kwa gasi pamitundu yosiyanasiyana ya 0.5 nA/ppm mpaka 9500 nA/ppm. Imalolezanso kutembenuka kosavuta kwa magawo apano kuchokera pa 5 µA mpaka 750 µA sikelo yonse.
Kupindula kwa LMP91000 kwa cell ndi transimpedance amplifier (TIA) kumatheka kudzera mu mawonekedwe a I 2C. Mawonekedwe a I 2C atha kugwiritsidwanso ntchito pozindikira ma sensor. Sensa yophatikizika ya kutentha imatha kuwerengedwa ndi wogwiritsa ntchito kudzera pa pini ya VOUT ndipo imagwiritsidwa ntchito popereka mawongolero owonjezera azizindikiro mu µC kapena kuyang'aniridwa kuti atsimikizire kutentha pa sensa.
LMP91000 imakonzedwa kuti igwiritse ntchito mphamvu zamagetsi ndipo imagwira ntchito pamtunda wa 2.7 mpaka 5.25 V. Zomwe zimagwiritsidwa ntchito panopa zingakhale zosakwana 10 μA. Kupulumutsa mphamvu kwina kumatheka pozimitsa amplifier ya TIA ndikufupikitsa maelekitirodi otengera ma elekitirodi ogwirira ntchito ndi chosinthira chamkati.
