The MAX86176 is a complete photoplethysmogram (PPG) and electrocardiogram (ECG) analog front-end (AFE) solution for wearable applications. The MAX30005 is a complete AFE solution for ECG only. Both AFEs offer high performance for fitness and clinical applications with ultra-low power for long battery life.

Both MAX86176 and MAX30005 feature an ECG channel, 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. In addition, the MAX86176 has a PPG data acquisition system supporting up to 6 LEDs and 4 photodiode inputs, which is fully synchronized with the ECG signal path. The MAX86176/MAX30005 can operate with either internal or external clock. The MAX86176/MAX30005 are designed to meet IEC 60601-2-47 Ambulatory ECG Systems monitoring compliance for even the most challenging dry electrode applications.

The MAX86176/MAX30005 are available in a 6x6 36-bump wafer-level packages (WLP), operating over the -40ºC to +85ºC temperature range.

Product Detail

The MAX86176 evaluation kit (EV kit) provides a platform to evaluate the functionality and features of the MAX86176 with photoplethysmogram (PPG) and electrocardiogram (ECG) measurement capabilities. The EV kit allows for flexible hardware and software configurations to help the user quickly learn how to configure and optimize the MAX86176 for their own applications.

The MAX86176 is a complete PPG and ECG analog front-end solution that consists of two optical readout channels and one single-lead ECG channel that can operate simultaneously. The optical readout channels support up to 6 LEDs and 4 photodiode inputs.

The MAX86176 EV kit consists of two boards. MAXSENSORBLE_EVKIT_B is the microcontroller (MCU) board while MAX86176_EVKIT_A is the sensor board containing the MAX86176. To enable PPG and ECG measurement capabilities, the sensor board also contains 3 LEDs (red, green, and IR), 3 discrete photodiodes (Vishay VEMD8080), a 3 LED, 1 photodiode module (Osram SFH7050), and component configurations on the ECG channel. The EV kit can be powered through USB connection to PC using a USB-C to USB-A cable or a LiPo Battery. The EV kit communicates with MAX86176GUI (should be installed in user’s system) using Bluetooth® built into Windows (Win BLE). The EV kit contains with the latest firmware but comes with the programming circuit board MAXDAP-TYPE-C in case a firmware change is needed.
