♠ Best-in-Class Optical Pulse Oximeter ndi Sensor Yogunda Pamtima pa Thanzi Lovala
MAX86140/MAX86141 ndi ultra-low-power, ophatikizika kwathunthu, optical data acquisition systems.Kumbali ya transmitter, MAX86140/MAX86141 ili ndi madalaivala atatu amakono a LED omwe amatha kukonzedwa kuti aziyendetsa mpaka ma LED asanu ndi limodzi pogwiritsa ntchito 3x2:1 mux yakunja.Ndi zida ziwiri za MAX86140/MAX86141 zomwe zimagwira ntchito ngati akapolo, madalaivala a LED amatha kuyendetsa mpaka ma LED khumi ndi awiri pogwiritsa ntchito 3x2:1 mux yakunja.Kumbali yolandila,
MAX86140 imakhala ndi njira imodzi yowerengera yowerengera, pomwe MAX86141 ili ndi njira ziwiri zowerengera zomwe zimatha kugwira ntchito nthawi imodzi.Zidazi zili ndi lownoise sign conditioning analog front-end (AFE) kuphatikizapo 19-bit ADC, dera lotsogolera makampani ambient light cancellation (ALC), ndi picket mpanda kuzindikira ndi kusintha ntchito.Chifukwa cha kuchepa kwa mphamvu yamagetsi, kukula kwapang'onopang'ono, kugwiritsa ntchito mosavuta, komanso kukana kuwala kwamakampani omwe amatsogolera ku MAX86140/MAX86141, zipangizozi ndi zabwino kwa mitundu yosiyanasiyana ya optical-sensing applications, monga pulse oximetry ndi kuzindikira kugunda kwa mtima.
MAX86140/MAX86141 imagwira ntchito pa 1.8V main supply voltage ndi 3.1V mpaka 5.5V LED yoyendetsa magetsi.Zida zonsezi zimathandizira mawonekedwe ogwirizana a SPI komanso ntchito yodziyimira yokha.Chida chilichonse chimakhala ndi FIFO yayikulu yokhala ndi mawu 128.MAX86140/MAX86141 ikupezeka mu phukusi la compact wafer-level package (WLP) (2.048 x 1.848mm) yokhala ndi phula la mpira wa 0.4mm.
