Description

The MAXREFDES1043 is designed for SpO2 measurements based on Maxim’s new-generation biosensor—the MAX30102. The MAXREFDES1043 is a high-accuracy, low-power, small-size, and easily implemented design that can monitor SpO2 levels using red and IR LEDs. The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices. It operates on a single 1.8V power supply and a separate 3.3V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all time.
