♠ Pai-i-Class Optical Pulse Oximeter me te Pūoko Reiti Manawa mo te Hauora Wearable
Ko te MAX86140/MAX86141 he tino-iti-te mana, he tino whakauru, he punaha tango raraunga whatu.I te taha o te kaiwhakawhiti, ko te MAX86140/MAX86141 e toru nga taraiwa LED o naianei ka taea te whakarite kia eke ki te ono nga rama ma te whakamahi i te 3x2:1 mux o waho.Ma nga taputapu MAX86140 / MAX86141 e rua e mahi ana i te aratau rangatira-pononga, ka taea e nga taraiwa LED te taraiwa ki te tekau ma rua nga LED ma te whakamahi i te 3x2: 1 mux o waho.I te taha o te kaiwhiwhi,
Ko te MAX86140 he hongere panui whatu kotahi, ko te MAX86141 e rua nga hongere panui whatu ka taea te mahi i te wa kotahi.Ko nga taputapu he iti te haruru tohu tohu tairitenga o mua-mutunga (AFE) tae atu ki te 19-bit ADC, he ara iahiko whakakorenga rama ambient (ALC) arataki-ahumahi, me te taiapa picket hei kimi me te whakakapi mahi.Na te iti o te kohi hiko, te rahi kiato, te ngawari o te whakamahi, me te kaha ki te whakakore i te rama ambient-ahumahi o MAX86140/MAX86141, he pai nga taputapu mo te tini o nga momo tono whakaata-a-mata, penei i te pulse oximetry me te kitenga o te ngakau.
Ko te MAX86140 / MAX86141 e mahi ana i runga i te 1.8V ngaohiko tuku matua me te 3.1V ki te 5.5V LED ngaohiko tuku taraiwa.Ka tautokohia e nga taputapu e rua tetahi atanga hototahi SPI paerewa me te mahi motuhake.Kei ia taputapu he FIFO nui 128-kupu i hangaia.Kei te waatea te MAX86140/MAX86141 i roto i te kohinga taumata-wafer (WLP) (2.048 x 1.848mm) me te 0.4mm te papa poroporo.
