O le LMP91000 ose polokalamemable analog front-end (AFE) mo le fa'aoga i le micro-power electrochemical sensing applications.E maua ai se fa'ai'uga ala fa'ailo atoatoa i le va o se masini ma se microcontroller e fa'atupuina ai se voluma fa'aola e fa'atatau i le sela o lo'o iai nei.O le polokalame a le LMP91000 e mafai ai ona lagolagoina le tele o masini eletise e pei o le 3-lead toxic gas sensors ma le 2-lead galvanic cell sensors ma se mamanu e tasi e ese mai i le tele o fofo eseese.O le LMP91000 e lagolagoina le maaleale o le kesi i luga ole laiga ole 0.5 nA/ppm i le 9500 nA/ppm.E fa'atagaina ai fo'i se fa'aliliuga faigofie o va'aiga o lo'o iai nei mai le 5 μA i le 750 μA le fua atoa.

O le LMP91000's adjustable cell bias and transimpedance amplifier (TIA) gain e mafai ona fa'apolokalameina i le I 2C interface.O le I 2C fa'aoga e mafai foi ona fa'aoga mo su'esu'ega masini.E mafai ona faitau e le tagata fa'aoga se masini vevela tu'ufa'atasia e ala i le VOUT pine ma fa'aoga e tu'uina atu ai fa'ailoga fa'aopoopo fa'asa'oga i le µC pe mata'itūina e fa'amaonia tulaga o le vevela i le masini.

O le LMP91000 ua sili ona lelei mo talosaga micro-power ma faʻagaoioia i luga ole laina eletise ole 2.7 i le 5.25 V. O le aofaʻi o le taimi nei e mafai ona itiiti ifo i le 10 μA.E mafai ona fa'asaoina atili le eletise e ala i le tapeina o le fa'amalo o le TIA ma fa'apu'upu'u le eletise fa'asino i le eletise galue ma se ki totonu.
