EVALUATION KIT AVAILABLE MAX86160 Integrated Heart-Rate Sensor for In-Ear Applications General Description Benefits and Features The MAX86160 is an integrated heart rate monitor sensor Miniature 4.3mm x 2.8mm x 1.45mm 18-pin Optical module designed for the demanding requirements of Module mobile, wearable, and hearable devices. It includes Optical-Grade, Robust Glass Eliminates Customer internal LEDs, photo-detector, and low-noise electronics Cover Glass with high-dynamic-range ambient light rejection. This High In-Band 13Hz Signal-to-Noise Ratio (SNR) integrated product is a complete system solution, and Reflective Heart Rate Monitor and Medical-Grade comes with plug-and-play software and robust algorithms Pulse Oximeter to give meaningful outputs to the user with minimal Ultra Low-Power Operation for Mobile Device additional design effort. The MAX86160 sensor module Zero-Power Shutdown Current (0.7A, typ) takes care of the most challenging parts of the design for -40C to +85C Operating Temperature Range fast time-to-market in mobile and wearable devices. The MAX86160 operates on a 1.8V supply voltage, with Applications a separate 3.3V/5.0V power supply for the internal LEDs. Wearable and Hearable Devices Communication to and from the module occurs entirely Smartphones/Tablets 2 through a standard I C-compatible interface. The module Disposable Patch Sensors can be shut down through software with near zero standby Fitness Assistant Devices current, allowing the power rails to remain powered at all times.
