MAX30102 High-Sensitivity Pulse Oximeter and Heart-Rate Sensor for Wearable Health General Description Benefits and Features The MAX30102 is an integrated pulse oximetry and Heart-Rate Monitor and Pulse Oximeter Sensor in heart-rate monitor module. It includes internal LEDs, LED Reflective Solution photodetectors, optical elements, and low-noise electronics Tiny 5.6mm x 3.3mm x 1.55mm 14-Pin Optical Module with ambient light rejection. The MAX30102 provides a Integrated Cover Glass for Optimal, Robust complete system solution to ease the design-in process Performance for mobile and wearable devices. Ultra-Low Power Operation for Mobile Devices The MAX30102 operates on a single 1.8V power supply Programmable Sample Rate and LED Current for and a separate 5.0V power supply for the internal LEDs. Power Savings 2 Communication is through a standard I C-compatible Low-Power Heart-Rate Monitor (< 1mW) interface. The module can be shut down through software Ultra-Low Shutdown Current (0.7A, typ) with zero standby current, allowing the power rails to Fast Data Output Capability remain powered at all times. High Sample Rates Applications Robust Motion Artifact Resilience High SNR Wearable Devices Fitness Assistant Devices -40C to +85C Operating Temperature Range Ordering Information appears at end of data sheet.
