♠ Qhov zoo tshaj plaws-hauv-Class Optical Pulse Oximeter thiab Lub plawv-Rate Sensor rau Wearable Health
MAX86140 / MAX86141 yog ultra-low-power, tag nrho kev koom ua ke, kho qhov muag cov ntaub ntawv tau txais cov tshuab. Nyob rau sab transmitter, MAX86140 / MAX86141 muaj peb lub programmable high-tam sim no LED tsav tsheb uas tuaj yeem teeb tsa kom tsav mus txog rau rau LEDs siv 3x2: 1 mux sab nraud. Nrog ob lub MAX86140 / MAX86141 cov khoom siv ua haujlwm hauv hom qhev, LED tsav tsheb tuaj yeem tsav mus txog kaum ob lub LEDs siv lub 3x2: 1 mux sab nraud. Nyob rau sab receiver,
MAX86140 muaj ib qho kev nyeem ntawv kho qhov muag tib lub sijhawm, thaum MAX86141 muaj ob txoj kev nyeem ntawv kho qhov muag uas tuaj yeem ua haujlwm ib txhij. Cov khoom siv muaj cov teeb liab qis qis qis qis qis qis qis qis qis qis hauv qab-kawg (AFE) suav nrog 19-ntsis ADC, kev lag luam-ua ambient lub teeb tshem tawm (ALC) Circuit Court, thiab lub laj kab picket nrhiav thiab hloov ua haujlwm. Vim yog lub zog siv tsawg, qhov loj me, kev siv yooj yim, thiab kev lag luam-ua ambient lub teeb rejection muaj peev xwm ntawm MAX86140 / MAX86141, cov cuab yeej zoo tagnrho rau ntau yam kev siv kho qhov muag, xws li pulse oximetry thiab lub plawv dhia ntsuas.
Lub MAX86140 / MAX86141 ua haujlwm ntawm 1.8V lub ntsiab khoom siv hluav taws xob thiab 3.1V rau 5.5V LED tsav tsheb muab hluav taws xob. Ob lub cuab yeej txhawb nqa tus qauv SPI tshaj qhov sib txuas thiab kev ua haujlwm siab. Txhua lub cuab yeej muaj qhov loj 128-lo lus built-in FIFO. MAX86140 / MAX86141 yog muaj nyob rau hauv compact wafer-level pob (WLP) (2.048 x 1.848mm) nrog 0.4mm pob suab.
