AFE4950 Integrated Analog Front-End (AFE)

Texas Instruments AFE4950 Integrated Analog Front-End (AFE) is for the synchronized signal acquisition of PPG and ECG signals. The Texas Instruments AFE4950 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 for continuous, low-power monitoring of the impedance between electrodes.
