AFE4950EVM
AFE4950 evaluation module for ultra-small integrated AFE for wearable optical heart-rate monitoring
AFE4950EVM
Overview
The AFE4950 evaluation module (EVM) is designed to expedite evaluation and system-development activities related to the AFE4950 product. AFE4950 is an analog front end (AFE) for synchronized signal acquisition of PPG and ECG signals. AFE4950 can also be used for optical biosensing applications, such as heart-rate monitoring (HRM) and saturation of peripheral capillary oxygen (SpO2).
The ECG signal chain supports two- and three-electrode configurations and has an integrated right-leg drive (RLD) buffer. The ECG signal chain can also be repurposed to perform a continuous, low-power monitoring of the impedance between a pair of electrodes.
