Finger heart rate and pulse oximeter smart sensor with digital signal processing
The MAX77860 is a high-performance single input switch mode charger that features USB Type-C CC detection capability in addition to reverse boost capability and a Safeout LDO.
The MAXREFDES220# reference design provides everything you need to quickly prototype your product to measure finger-based heart rate and blood oxygen saturation level (SpO2).
The MAX30101 and the MAX32664 provide an integrated hardware and software solution for multiple finger-based applications. The MAX32664 firmware provides digital signal processing to process the data. The reference design also includes a tri-axis accelerometer to compensate for motion artifacts.
