MAX86150EVSYS#

MAX86150 is a first-of-a kind biosensor module, comprised of internal LEDs, photodetectors and an ECG analogue front-end to provide highly accurate, FDA-certifiable PPG and ECG performance in compact, power-saving designs, including mobile phones, laptops, tablets and smart speakers. Delivering synchronized PPG and ECG measurements has been challenging because designers had to use two separate biosensors that consume more board space and power than a mobile device can typically afford. Achieving high accuracy in the measurements has also been challenging, especially where sensor sensitivity might be impacted by low perfusion levels or dry skin. The MAX86150 overcomes these challenges, sampling both PPG and ECG simultaneously to provide the highest sensitivity of pulse transit time. To reduce battery drain, the module can be shut down through software with near-zero standby current, allowing the power rails to remain powered at all times.

• Market leading CMMR (Common Mode Rejection Ratio) of 136dB provides high accuracy.
• 100mA-capable, high-dynamic-range LED driver enables higher sensitivity on an array of skin types.
• Low impedance contact for the ECG sensor enables more accurate measurements, even in cases of dry skin.
• Ultra-low shutdown current of 0.7μA typical minimizes power drain for long battery life.
• Power consumption less than the closest competitive device further extends battery life compared to competitive solutions.
• Dry electrode operation eliminates the need for gels, fluids and sticky or wet pads on other parts of the body to obtain accurate readings.
• Integrating an ECG sensor with an optical PPG sensor saves space and provides much more functionality without requiring a third electrode.
