♠ Eyona-yeyona Klasi iOptical Pulse Oximeter kunye neSensor yeNtliziyo yeMpilo
I-MAX86140/MAX86141 i-ultra-low-power, ihlanganiswe ngokupheleleyo, iinkqubo zokufumana idatha ye-optical. Kwicala lokuhambisa, i-MAX86140/MAX86141 inee-drive ze-LED ezintathu ezicwangcisiweyo eziphezulu zangoku ezinokuthi ziqwalaselwe ukuqhuba ukuya kwii-LED ezintandathu usebenzisa i-3x2: i-1 mux yangaphandle. Ngezixhobo ezimbini ze-MAX86140 / MAX86141 ezisebenza kwimodi ye-master-slave, abaqhubi be-LED banokuqhuba ukuya kwii-LED ezilishumi elinambini usebenzisa i-3x2: i-1 mux yangaphandle. Kwicala lomamkeli,
I-MAX86140 iqulathe itshaneli yokufundwa kwe-optical enye, ngelixa i-MAX86141 ineendlela ezimbini zokufunda ezinokuthi zisebenze ngaxeshanye. Izixhobo zine-lownoise signal conditioning analog front-end (AFE) kuquka i-19-bit ADC, i-industrial-lead ambient light cancellation (ALC) isiphaluka, kunye nocingo lwe-picket lufumana kwaye luthathe indawo yomsebenzi. Ngenxa yokusetyenziswa kwamandla aphantsi, ubungakanani be-compact, ukusetyenziswa lula, kunye ne-industry-lead ambient light rejection capability ye-MAX86140/MAX86141, izixhobo zifanelekile kwiindidi ezininzi ze-optical-sensing applications, ezifana ne-pulse oximetry kunye nokufumanisa izinga lentliziyo.
I-MAX86140 / MAX86141 isebenza kwi-voltage ye-1.8V engundoqo yokubonelela kunye ne-3.1V ukuya kwi-5.5V ye-LED yombane wokubonelela ngomqhubi. Zombini izixhobo zixhasa ujongano oluqhelekileyo lwe-SPI kunye nokusebenza ngokuzimela ngokupheleleyo. Isixhobo ngasinye sine-128-igama elikhulu eyakhelwe-ngaphakathi i-FIFO. I-MAX86140/MAX86141 ifumaneka kwi-compact wafer-level package (WLP) (2.048 x 1.848mm) kunye ne-0.4mm yebhola.
