MAX86140 / MAX86141 ni ultra-power-power, ihuriweho rwose, sisitemu yo kubona amakuru neza. Kuruhande rwa transmitter, MAX86140 / MAX86141 ifite ibinyabiziga bitatu bishobora gutegurwa cyane-bigezweho bya LED bishobora gushyirwaho kugirango bigere kuri LED zigera kuri esheshatu ukoresheje 3x2: 1 mux yo hanze. Hamwe nibikoresho bibiri bya MAX86140 / MAX86141 bikora muburyo bwa shebuja-imbata, abashoferi ba LED barashobora gutwara LED zigera kuri cumi na zibiri ukoresheje 3x2: 1 mux yo hanze. Kuruhande rwabakiriye,
MAX86140 igizwe numuyoboro umwe wo gusoma wa optique, mugihe MAX86141 ifite imiyoboro ibiri yo gusoma ishobora gukora icyarimwe. Ibikoresho bifite ibimenyetso bya lownoise byerekana analog imbere-end (AFE) harimo 19-bit ADC, inganda ziyobora inganda zangiza urumuri (ALC), hamwe nuruzitiro rwa piketi rusanga kandi rugasimbuza imikorere. Bitewe no gukoresha ingufu nke, ingano yoroheje, koroshya imikoreshereze, hamwe ninganda ziyobora ibidukikije byanga urumuri rwa MAX86140 / MAX86141, ibikoresho nibyiza muburyo butandukanye bwo gukoresha optique-sensing, nka pulse oximetry no kumenya umuvuduko wumutima.
MAX86140 / MAX86141 ikora kuri voltage ya 1.8V itanga amashanyarazi hamwe na 3.1V kugeza 5.5V LED itanga amashanyarazi. Ibikoresho byombi bishyigikira interineti isanzwe ya SPI hamwe nibikorwa byigenga byuzuye. Buri gikoresho gifite ijambo rinini 128-ryubatswe muri FIFO. MAX86140 / MAX86141 iraboneka muri pake ya wafer yo murwego (WLP) (2.048 x 1.848mm) hamwe na 0.4mm yumupira.
