SFH7018 MULTILED®

ams OSRAM's 3-in-1 high-quality multi-emitters offer green, red, and infrared (IR) in one package

Image of ams-OSRAM's SFH7018 MultiLEDams OSRAM's SFH7018A and SFH7018B MULTILED devices are next-generation 3-in-1 multi-emitters that offer green, red, and IR in one package. These high-performance emitters are designed for monitoring heart rate and SpO2. The MULTILED devices offer a higher accuracy due to an optimized light output and reduced interference between the dies. The highly efficient QFN package features a unique two-cavity design.

The MULTILED SFH 7018A focuses on a low forward voltage (2.65 VF typical) at a high current (200 mA). The MULTILED SFH 7018B focuses on maximum radiant intensity. Compared to the SFH 7016, these emitters are 2x brighter for green and more than 45% brighter for red and IR.

Features
  • Competitively priced high-quality multi-emitter solutions for end-product classes
  • Best-in-class LED efficiency and brightness:
    • Minimal energy consumption
    • Improved performance for dark skin
    • Ultra-low-forward voltage enables direct driving from the battery at the max. current (MULTILED SFH 7018A)
  • Separate cavity for the red/IR emitter allows for a matched optical path improving the SpO2 measurement accuracy
Applications
  • Integrated light source modules:
    • Vital sign monitoring: smart watches, fitness bands, and others
  • In combination with a detector (photodiode), an analog front-end IC, and a suitable algorithm
    • Measuring heart rate, SpO2, breath rate, blood pressure trends, heart rate variability, and other parameters
