♠ LMP91000 Sensor AFE System: Configurable AFE Potentiostat bakeng sa Lits'ebetso tsa Low-Power ChemicalSensing
LMP91000 ke "analog front-end" (AFE) e ka sebelisoang lits'ebetsong tsa matla a micro-electrochemical sensing. E fana ka tharollo e feletseng ea tsela ea pontšo pakeng tsa kutlo le microcontroller e hlahisang motlakase o hlahisoang o lekanang le oa hona joale oa sele. The LMP91000's programmability e e nolofalletsa ho ts'ehetsa li-sensor tse ngata tsa electrochemical tse kang li-sensor tsa khase e chefo ea 3-lead le li-2-lead galvanic cell sensors tse nang le moralo o le mong ho fapana le litharollo tse ngata tse fapaneng. LMP91000 e ts'ehetsa maikutlo a khase ho tloha ho 0.5 nA/ppm ho isa ho 9500 nA/ppm. E boetse e lumella phetoho e bonolo ea mekhahlelo ea hajoale ho tloha ho 5 µA ho isa ho 750 µA sekala se felletseng.
The LMP91000's e fetolehang ea cell bias le transimpedance amplifier (TIA) e ka lokisoa ka sebopeho sa I 2C. Khokahano ea I 2C e ka boela ea sebelisoa bakeng sa tlhahlobo ea kutlo. Sensor e kopantsoeng ea mocheso e ka baloa ke mosebelisi ka pini ea VOUT mme e sebelisetsoa ho fana ka tokiso e eketsehileng ea matšoao ho µC kapa ho hlahlojoa ho netefatsa maemo a mocheso ho sensor.
LMP91000 e ntlafalitsoe bakeng sa lisebelisoa tsa matla a manyenyane 'me e sebetsa ho feta tekanyo ea motlakase ea 2.7 ho ea ho 5.25 V. Kakaretso ea tšebeliso ea hona joale e ka ba tlase ho 10 μA. Ho boloka matla a eketsehileng ho ka khoneha ka ho tima sebuela-hōle sa TIA le ho khutsufatsa eleketrode ea referense ho eleketrode e sebetsang ka switjha e ka hare.
