Description

The MAX86160 is an integrated heart rate monitor sensor module designed for the demanding requirements of mobile, wearable, and hearable devices. It includes internal LEDs, photo-detector, and low-noise electronics with high-dynamic-range ambient light rejection. This integrated product has evaluation software available that includes algorithms for detecting heart rate. The MAX86160 sensor module takes care of the most challenging parts of the design for fast time-to-market in mobile and wearable devices.

The MAX86160 operates on a 1.8V supply voltage, with a separate 3.3V/5.0V power supply for the internal LEDs. Communication to and from the module occurs entirely through a standard I²C-compatible interface. The module can be shut down through software with near zero standby current, allowing the power rails to remain powered at all times.
