The MAX86150 from Maxim Integrated Products integrates internal LEDs, photodetectors and an ECG analog front-end (AFE) to provide highly accurate, FDA-certifiable PPG and ECG performance in compact, power-saving designs, including mobile phones, laptops, tablets and smart speakers.
The 3.3×6.6×1.3mm, 22-pin optical module samples 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. At 136dB, the module’s common mode rejection ratio (CMRR) is the highest on the market. Its 100mA-capable, high-dynamic-range LED driver enables higher sensitivity on an array of skin types. A low-impedance contact for the ECG sensor enables more accurate measurements, even in cases of dry skin.
