♠ Heerka ugu Wanaagsan ee Oximeter-ka garaaca indhaha iyo garaaca wadnaha ee caafimaadka la xidhan karo
MAX86140/MAX86141 waa awood aad u hooseeysa, oo gebi ahaanba isku dhafan, nidaamyada xogta indhaha.Dhinaca gudbiyaha, MAX86140/MAX86141 waxay leeyihiin saddex darawal oo LED-sare oo hadda jira oo barnaamijaysan kuwaas oo loo habayn karo inay kaxeeyaan ilaa lix LED iyadoo la adeegsanayo 3x2: 1 mux dibadda ah.Iyadoo laba qalab oo MAX86140/MAX86141 ah oo ku shaqeeya habka addoonsiga, darawalada LED-yada waxay wadi karaan ilaa laba iyo toban LEDs iyagoo isticmaalaya 3x2: 1 mux.Dhinaca qaataha,
MAX86140 waxa uu ka kooban yahay hal kanaal oo wax akhriska indhaha ah, halka MAX86141 uu leeyahay laba kanaal wax akhrinta indhaha oo isku mar shaqayn kara.Qalabku waxay leeyihiin dhawaaqa dhawaaqa hoose ee qaboojiyaha analoogga hore-dhamaadka (AFE) oo ay ku jiraan 19-bit ADC, wareegtada baabiinta iftiinka jawiga-warshadaha (ALC), iyo xayndaabka deyrka lagu ogaado oo beddelo shaqada.Sababo la xiriira isticmaalka awoodda hooseeya, cabbirka is haysta, fududaynta isticmaalka, iyo warshadaha-lead-ka-hortagga iftiinka iftiinka iftiinka ee awoodda MAX86140/MAX86141, aaladuhu waxay ku habboon yihiin noocyo kala duwan oo codsiyo-dareen-muuqaal ah, sida oximetry garaaca wadnaha iyo ogaanshaha garaaca wadnaha.
MAX86140/MAX86141 wuxuu ku shaqeeyaa 1.8V danab sahayda ugu weyn iyo 3.1V ilaa 5.5V LED danab sahayda darawalka.Labada qalabba waxay taageeraan is-dhexgalka caadiga ah ee SPI iyo hawlgal si buuxda u madaxbannaan.Qalab kastaa wuxuu leeyahay 128-erey oo weyn oo FIFO ku dhex dhisan.MAX86140/MAX86141 waxaa lagu heli karaa xirmo heer wafer ah oo is haysta (WLP) (2.048 x 1.848mm) oo leh 0.4mm garoon kubbadda.
