♠ Oximeter Pulse Optical maikaʻi loa ma ka papa a me ka ʻenekona puʻuwai no ke olakino hiki ke hoʻohana.
ʻO ka MAX86140/MAX86141 he ultra-haʻahaʻa-mana, hoʻohui piha ʻia, nā ʻōnaehana ʻikepili ʻike. Ma ka ʻaoʻao transmitter, loaʻa i ka MAX86140/MAX86141 ʻekolu mau mea hoʻokele LED kiʻekiʻe o kēia manawa hiki ke hoʻonohonoho ʻia e hoʻokele i ʻeono mau LED me ka hoʻohana ʻana i kahi 3x2:1 mux waho. Me ʻelua mau polokalamu MAX86140/MAX86141 e hana ana ma ke ʻano master-slave, hiki i nā mea hoʻokele LED ke hoʻokele i ʻumikumamālua mau LED me ka hoʻohana ʻana i kahi 3x2:1 mux waho. Ma ka aoao hookipa,
Loaʻa iā MAX86140 kahi kaila heluhelu optical hoʻokahi, ʻoiai ʻo ka MAX86141 he ʻelua mau kaha heluhelu optical hiki ke hana i ka manawa like. Loaʻa i nā hāmeʻa ka lownoise signal conditioning analog front-end (AFE) me ka 19-bit ADC, kahi ʻoihana alakaʻi ambient ambient light cancellation (ALC) kaapuni, a me kahi pā picket ʻike a pani i ka hana. Ma muli o ka hoʻohana haʻahaʻa haʻahaʻa, ka nui paʻa, ka maʻalahi o ka hoʻohana ʻana, a me ka hiki ke hōʻole i ka māmā ambient alakaʻi ʻoihana o MAX86140/MAX86141, kūpono nā mea hana no nā ʻano noiʻi optical-sensing, e like me ka pulse oximetry a me ka ʻike ʻana i ka puʻuwai.
Hoʻohana ʻia ka MAX86140/MAX86141 ma ka 1.8V nui lako uila a me ka 3.1V a 5.5V LED mea hoʻokele uila uila. Kākoʻo nā ʻaoʻao ʻelua i kahi interface kūpono SPI maʻamau a me ka hana autonomous piha. Loaʻa i kēlā me kēia hāmeʻa kahi FIFO nui 128-huaʻōlelo i kūkulu ʻia. Loaʻa ka MAX86140/MAX86141 i loko o ka pūʻolo wafer-level paʻakikī (WLP) (2.048 x 1.848mm) me ka pitch pōpō 0.4mm.
