ʻO ka LMP91000 kahi papahana analogue front-end (AFE) no ka hoʻohana ʻana i nā noi ʻike electrochemical sensing micro-power. Hāʻawi ia i kahi hopena ala hōʻailona holoʻokoʻa ma waena o kahi mea ʻike a me kahi microcontroller e hoʻohua ai i kahi volena puka e like me ke ʻano o ke kelepona. Hiki i ka LMP91000 ka polokalamu ke kākoʻo i nā mea ʻike electrochemical he nui e like me 3-lead toxic gas sensors a me 2-lead galvanic cell sensors me ka hoʻolālā hoʻokahi e kūʻē i nā hoʻonā ʻokoʻa lehulehu. Kākoʻo ka LMP91000 i ka ʻike kinoea ma luna o ka laulā o 0.5 nA/ppm a i 9500 nA/ppm. Hiki iā ia ke hoʻololi maʻalahi i nā pae o kēia manawa mai 5 µA a i 750 µA piha piha.
ʻO ka LMP91000 hiki ke hoʻololi i ka cell bias a me ka transimpedance amplifier (TIA) loaʻa ka programmable ma o ka I 2C interface. Hiki ke hoʻohana ʻia ka interface I 2C no nā diagnostics sensor. Hiki ke heluhelu ʻia e ka mea hoʻohana ma ka pine VOUT a hoʻohana ʻia e hāʻawi i ka hoʻoponopono hōʻailona hou i ka µC a i ʻole ke nānā ʻia e hōʻoia i nā kūlana wela ma ka ʻike.
Hoʻolālā ʻia ka LMP91000 no nā noi micro-power a ke hana nei ma luna o kahi kaha uila o 2.7 a 5.25 V. ʻO ka nui o ka hoʻohana ʻana i kēia manawa hiki ke emi ma lalo o 10 μA. Hiki ke mālama hou i ka mana ma ka hoʻopau ʻana i ka amplifier TIA a pōkole i ka electrode kuhikuhi i ka electrode hana me kahi hoʻololi kūloko.
