♠ I-Best-in-Class Optical Pulse Oximeter kanye Nenzwa Yokushaya Kwenhliziyo Yempilo Egqokekayo
Ama-MAX86140/MAX86141 angamandla aphansi kakhulu, ahlanganiswe ngokuphelele, amasistimu wokutholwa kwedatha yokubona. Ngasohlangothini lwe-transmitter, i-MAX86140/MAX86141 inamadrayivu e-LED amathathu ahlelekayo aphezulu angalungiselelwa ukushayela ama-LED ayisithupha kusetshenziswa i-3x2:1 mux yangaphandle. Ngamadivayisi amabili e-MAX86140/MAX86141 asebenza kumodi yesigqila esiyinhloko, abashayeli be-LED bangashayela ama-LED afinyelela kwayishumi nambili besebenzisa i-3x2:1 mux yangaphandle. Ngasohlangothini lomamukeli,
I-MAX86140 iqukethe isiteshi sokufunda sokubona esisodwa, kuyilapho i-MAX86141 inamashaneli amabili okufunda okubonakalayo angasebenza kanyekanye. Amadivayisi ane-lownoise signal conditioning analog front-end (AFE) okuhlanganisa i-19-bit ADC, i-industrial-lead ambient light cancellation circuit (ALC), kanye nocingo lwe-picket detect and replace function. Ngenxa yokusetshenziswa kwamandla okuphansi, usayizi ohlangene, ukusetshenziswa kalula, nekhono lokwala ukukhanya okuholela embonini kwe-MAX86140/MAX86141, amadivayisi alungele izinhlelo zokusebenza ezihlukahlukene zokuzwa optical, ezifana ne-pulse oximetry nokutholwa kwesilinganiso senhliziyo.
I-MAX86140/MAX86141 isebenza ku-voltage eyinhloko engu-1.8V kanye ne-3.1V kuya ku-5.5V ye-LED yokuhambisa umshayeli wevolthi. Womabili amadivaysi asekela isixhumi esibonakalayo esihambisanayo se-SPI nokusebenza okuzilawula ngokugcwele. Idivayisi ngayinye ine-FIFO enkulu eyakhelwe ngaphakathi enamagama angu-128. I-MAX86140/MAX86141 iyatholakala ku-compact wafer-level package (WLP) (2.048 x 1.848mm) ene-pitch yebhola engu-0.4mm.
