MAX30110 Description
The MAX30110 is a plete optical pulse oximetry and heart rate detection integrated analog front-end. The MAX30110 has a high-resolution, optical readout signalprocessing channel with built-in ambient light cancellation, as well as high-current LED driver DACs, to form a plete optical readout signal chain. With external LED(s) and photo diode(s), the MAX30110 offers the lowest power, highest performance heart rate...
