AFE4950 Ultra-Small, Integrated AFE for Wearable Optical Heart-Rate Monitoring, SpO2 and Electrical Bio-sensing datasheet (Rev. A)

 

 

DATA SHEET

 

The AFE4950 device is an analog front-end (AFE) for synchronized signal acquisition of PPG and ECG signals.

The device can also be used for optical bio-sensing applications, such as heart-rate monitoring (HRM) and saturation of peripheral capillary oxygen (SpO2).

The ECG signal chain supports 2- and 3-electrode configurations and has an integrated Right leg drive (RLD) buffer.

The ECG signal chain can also be used to do a continuous, low-power monitoring of the impedance between pair of electrodes.
