O le MAX86140/MAX86141 o le ultra-low-power, atoatoa tu'ufa'atasia, fa'aogaina fa'amatalaga fa'amatalaga. I le itu o le transmitter, o le MAX86140/MAX86141 o loʻo i ai ni taʻavale LED maualuga e tolu e mafai ona faʻaogaina e mafai ona faʻatulagaina e ave ai le ono LED e faʻaaoga ai le 3x2: 1 mux fafo. Faatasi ai ma le lua MAX86140 / MAX86141 masini o loʻo galue i le tulaga matai-pologa, e mafai e le avetaʻavale LED ona ave i luga le sefululua LED e faʻaaoga ai le 3x2: 1 mux fafo. I le itu e taliaina,
MAX86140 o lo'o i ai se alalaupapa faitau fa'apitoa e tasi, ae o le MAX86141 e lua ala faitau fa'aaliga e mafai ona fa'agaioi i le taimi e tasi. O masini o lo'o i ai le fa'amalo ole fa'ailo fa'amauina analog pito i luma (AFE) e aofia ai le 19-bit ADC, se ta'iala fa'aleaogaina o le malamalama fa'aola (ALC), ma se pa picket e iloa ma sui galuega. Ona o le maualalo o le eletise, lapopoa lapopoa, faigofie o le faʻaogaina, ma le faʻaogaina o le malamalama faʻafefe o le alamanuia o le MAX86140 / MAX86141, o masini e lelei mo le tele o ituaiga faʻaogaina o mea faʻapitoa, e pei o le pulse oximetry ma le suʻeina o le fatu.
O le MAX86140/MAX86141 o lo'o fa'agaoioia i luga o le 1.8V autu tu'uina atu eletise ma le 3.1V i le 5.5V LED aveta'avale eletise. O masini uma e lua o loʻo lagolagoina se faʻataʻitaʻiga talafeagai SPI ma faʻaoga tutoʻatasi atoatoa. O masini ta'itasi e iai le tele 128-upu o lo'o fausia i totonu FIFO. O le MAX86140/MAX86141 o lo'o maua i totonu o le pusa fa'ama'i (WLP) (2.048 x 1.848mm) ma le 0.4mm polo pitch.
