♠ LMP91000 Sensor AFE System: Configurable AFE Potentiostat yeLow-Power ChemicalSensing Application
Iyo LMP91000 ndeye programmable analog kumberi-kuguma (AFE) yekushandisa mune micro-simba electrochemical sensing application. Iyo inopa yakakwana chiratidzo nzira mhinduro pakati pe sensor uye microcontroller inogadzira inobuda voltage yakaenzana nesero razvino. Iyo LMP91000's programmability inoita kuti ikwanise kutsigira akawanda electrochemical sensors senge 3-lead ine chepfu gasi sensors uye 2-lead galvanic cell sensors ine imwe dhizaini inopesana neakawanda discrete mhinduro. Iyo LMP91000 inotsigira gasi sensitivities pamusoro pehuwandu hwe0.5 nA/ppm kusvika 9500 nA/ppm. Inobvumirawo kushandurwa kuri nyore kwemarenji azvino kubva pa5 µA kusvika ku750 µA yakazara chiyero.
Iyo LMP91000's inogadziriswa sero bias uye transimpedance amplifier (TIA) kuwana inorongeka kuburikidza neI 2C interface. Iyo I 2C interface inogona zvakare kushandiswa kune sensor diagnostics. Iyo yakabatanidzwa tembiricha sensor inogona kuverengerwa nemushandisi kuburikidza nepini yeVOUT uye inoshandiswa kupa imwe gadziriso yechiratidzo muµC kana kuongororwa kuti ione mamiriro ekushisa pane sensor.
Iyo LMP91000 yakagadziridzwa kune micro-power applications uye inoshanda pamusoro pehuwandu hwemagetsi e2.7 kusvika ku5.25 V. Iko kushandiswa kwemazuva ano kunogona kuva pasi pe10 μA. Kuwedzera kuchengetedza simba kunogoneka nekudzima TIA amplifier uye kupfupisa referensi electrode kune inoshanda electrode ine switch yemukati.
