♠ LMP91000 Sensor AFE System: Configurable AFE Potentiostat rau Low-Power ChemicalSensing Applications
LMP91000 yog ib qho programmable analog front-end (AFE) rau siv hauv micro-power electrochemical sensing daim ntaub ntawv. Nws muab tag nrho cov teeb liab txoj kev daws teeb meem ntawm lub sensor thiab microcontroller uas ua rau cov zis voltage proportional rau ntawm tes tam sim no. Lub LMP91000's programmability enables nws los txhawb ntau yam electrochemical sensors xws li 3-lead toxic gas sensors thiab 2-lead galvanic cell sensors nrog ib tug tsim ib qho piv txwv rau ntau yam kev daws teeb meem. LMP91000 txhawb nqa roj rhiab heev ntawm ntau yam ntawm 0.5 nA / ppm txog 9500 nA / ppm. Nws kuj tseem tso cai rau kev hloov pauv yooj yim ntawm qhov tam sim no ntawm 5 µA txog 750 µA tag nrho cov nplai.
LMP91000's adjustable cell bias thiab transimpedance amplifier (TIA) nce yog programmable los ntawm I 2C interface. I 2C interface kuj tseem siv tau rau kev kuaj mob sensor. Ib qho kev ntsuas kub sib xyaw tuaj yeem nyeem tau los ntawm tus neeg siv los ntawm VOUT tus pin thiab siv los muab cov teeb liab kho ntxiv hauv µC lossis saib xyuas kom paub tseeb qhov kub thiab txias ntawm lub sensor.
Lub LMP91000 yog optimized rau micro-power daim ntaub ntawv thiab ua hauj lwm tshaj ib tug voltage ntau ntawm 2.7 mus rau 5.25 V. Tag nrho cov tam sim no noj yuav tsawg tshaj li 10 μA. Kev txuag hluav taws xob ntxiv tuaj yeem ua tau los ntawm kev hloov ntawm TIA amplifier thiab luv luv cov ntaub ntawv siv hluav taws xob rau cov khoom siv hluav taws xob ua haujlwm nrog rau kev hloov sab hauv.
