LMP91000 bụ ihe ana-eme mmemme n'ihu-ọgwụgwụ analọgụ (AFE) maka ojiji na ngwa nhụta elektrọkem ike. Ọ na-enye ngwọta ụzọ mgbama zuru oke n'etiti ihe mmetụta na microcontroller nke na-emepụta voltaji mmepụta nke kwekọrọ na cell ugbu a. Mmemme LMP91000 na-enyere ya aka ịkwado ọtụtụ sensọ electrochemical dị ka sensọ gas na-egbu egbu 3 na sensọ cell galvanic 2-lead nwere otu imewe na-emegide ọtụtụ ngwọta pụrụ iche. LMP91000 na-akwado mmetụta gas karịrị 0.5 nA/ppm ruo 9500 nA/ppm. Ọ na-enye ohere maka ntụgharị dị mfe nke oke dị ugbu a site na 5 µA ruo 750 µA zuru oke.
The LMP91000 na-agbanwe agbanwe cell ele mmadụ anya n'ihu na transimpedance amplifier (TIA) bụ mmemme site na interface I 2C. Enwere ike iji interface I 2C mee nchọpụta ihe mmetụta. Onye ọrụ nwere ike ịgụ ihe mmetụta okpomọkụ agbakwunyere site na VOUT pin ma jiri nye mgbama mgbama ọzọ na µC ma ọ bụ nyochaa iji chọpụta ọnọdụ okpomọkụ na ihe mmetụta.
LMP91000 kachasị maka ngwa micro-power ma na-arụ ọrụ n'elu oke voltaji nke 2.7 ruo 5.25 V. Ngụkọta oriri ugbu a nwere ike ịbụ ihe na-erughị 10 μA. Enwere ike ịchekwa ike ọzọ site n'ịgbanyụọ ampilifaya TIA na mkpirisi electrode na-arụ ọrụ na ngbanwe nke ime.
