Maxim Integrated MAX30102 pulse oximeter and heart rate integrated sensor module

System designers can speed up time to market for wearable and healthcare products with the MAX30102 pulse oximeter and heart rate integrated sensor module from Maxim Integrated. The module provides a complete system to ease the design-in process for mobile and wearable devices.

Wearable equipment for vital-sign monitoring is evolving, and analog integration is at the heart of this. System-on-chip (SoC) and integrated module solutions are rapidly replacing discrete, multicomponent designs. The MAX30102 integrates red and IR LEDs to modulate LED pulses for oxygen saturation and heart rate measurements.

The module maintains a small size (5.6 x 3.3 x 1.55 mm) without sacrificing optical or electrical performance. It integrates internal LEDs, photodetectors, optical elements and low-noise electronics with ambient light rejection. An evaluation platform with the integrated module and an accelerometer enables users to quickly evaluate the module.

The ultralow-power product operates on a single 1.8 V power supply and a separate 5 V power supply for the internal LEDs. It has an operating temperature range of -40 to +85°C.
