Whakaahuatanga
Ko te AD9251 he monolithic, rua-hongere, 1.8 V supply, 14-bit, 20 MSPS / 40 MSPS / 65 MSPS / 80 MSPS analog-ki-digital converter (ADC).Kei roto i tetahi tauira-a iahiko-a-te-mahinga teitei me te tohutoro ngaohiko i runga i te maramara.Ka whakamahia e te hua te hoahoanga paipa rereke rereke me te arorau whakatika hapa whakaputa hei whakarato i te tika 14-bit i nga reiti raraunga MSPS 80 me te kii kaore he waehere ngaro i runga i te awhe pāmahana whakahaere katoa.He maha nga ahuatanga kei roto i te ADC i hangaia hei whakanui ake i te ngawari me te whakaiti i te utu o te punaha, penei i te karaka ka taea te whakarite me te tirohanga raraunga me te hanga tauira whakamatautau matihiko ka taea.Ko nga tauira whakamatautau mamati e waatea ana ko nga tauira whakatau me te pseudorandom kua hangaia, me nga tauira whakamatautau kua tautuhia e te kaiwhakamahi kua whakauruhia ma te atanga tauranga rangatū (SPI).Ko te whakaurunga karaka rereke e whakahaere ana i nga huringa huringa o roto katoa.Ka utua e te kaiwhakamau huringa mahi (DCS) mo nga rereketanga o te huringa mahi karaka i te wa e mau tonu ana te mahi ADC tino pai.Ko nga raraunga putanga mamati e whakaatuhia ana i roto i te ahua-rua, te waehere hina, te whakatakotoranga taapiri takirua ranei.Ka whakaratohia he karaka whakaputa raraunga (DCO) mo ia hongere ADC hei whakarite i te wa raka tika me te arorau whiwhi.Ka tautokohia nga taumata 1.8 V me te 3.3 V CMOS me nga raraunga whakaputa ka taea te taapiri ki runga i te pahi whakaputa kotahi.Kei te waatea te AD9251 i roto i te 64-arahi RoHS Compliant LFCSP, ka tohua i runga i te awhe pāmahana ahumahi (-40°C ki +85°C).
