Whakaahuatanga
Ko te ADM2490E he whakawhiti raraunga motuhake me te whakamarumaru ± 8 kV ESD e tika ana mo te tere tere, te whakawhitiwhiti korero-rua i runga i nga raina whakawhiti maha.He mea hoahoa mo nga raina whakawhiti taurite me te whai ki te ANSI TIA/EIA-485-A-1998 me ISO 8482: 1987(E).Ka whakamahia e te taputapu nga Analog Devices, Inc., te hangarau iCoupler® ki te whakakotahi i te whakawehe 2-hongere, he taraiwa raina rereke e toru nga kawanatanga, me tetahi kaiwhiwhi whakauru rereke ki te kete kotahi.Ko nga whakaputanga tuku rereke me nga whakaurunga kaikawe e whakaatu ana i nga hikoi whakaheke hiko e tiaki ana ki te ±8 kV ma te whakamahi i te tauira tinana tangata (HBM).Ko te taha arorau o te taputapu ka taea te hiko ki te 5 V, ki te 3 V ranei, engari ko te taha pahi e hiahia ana ki te tuku 5 V motuhake.Kei roto i te taputapu nga ahuatanga aukati o naianei me te katinga waiariki hei whakamarumaru mai i nga ara iahiko poto puta me nga ahuatanga ka kaha te tohenga o te pahi i te toreretanga o te hiko.Kei te waatea te ADM2490E i roto i te tinana whanui, 16-arahi SOIC kete me te mahi i runga i te -40°C ki te +105°C te awhe pāmahana.
