AD9649BCPZ-20 IC ADC 14BIT PIPELINE 32LFCSP

Whakaahuatanga

Ko te AD9649 he monolithic, kotahi te hongere 1.8 V supply, 14-bit, 20/40/65/80 MSPS analog-ki-digital converter (ADC).Kei te whakaatu i te tauira-a-te ara iahiko mahi 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 me te kowhiringa 1, 2, 4 ranei nga wehenga wehenga e whakahaere ana i nga huringa huringa o roto katoa.Ko nga raraunga putanga mamati e whakaatuhia ana i roto i te ahua-rua, te waehere hina, te whakatakotoranga taapiri takirua ranei.Ka tukuna he karaka whakaputa raraunga (DCO) hei whakarite i te wa raka tika me te arorau whiwhi.Ka tautokohia nga taumata 1.8 V me te 3.3 V CMOS.Kei te waatea te AD9649 i roto i te LFCSP 32-arahi RoHS-whakaritea, kua tohua i runga i te awhe pāmahana ahumahi (-40°C ki +85°C).
