MAX86176 PPG and ECG Analog Front-End (AFE)

Analog Devices MAX86176 PPG and ECG Analog Front-End (AFE) is a complete photoplethysmogram (PPG) and electrocardiogram (ECG) solution for wearable applications. The ECG channel of the MAX86176 features EMI filtering, internal lead biasing, AC and DC lead-off detection, right-leg drive, ultra-low power DC lead-on detection during standby mode, and extensive calibration voltages for built-in self-test. The PPG data acquisition system supports up to 6 LEDs and 4 photodiode inputs, which are fully synchronized with the ECG signal path. The MAX86176 can operate with either an internal or external clock. The device is designed to meet IEC 60601-2-47 Ambulatory ECG Systems monitoring compliance for even the most challenging dry electrode applications.
