TIDA-00311

Miniaturized Pulse Oximeter Reference Design

TIDA-00311

Design files

Overview

This reference design is for a miniturized pulse oximeter specifically designed for high end clinical applications. The small form factor module can easily simplify and accelerate pulse oximeter system design. Featuring TI's AFE4403 Analog Front End for interfacing with the LED and Photodiode sensors, this design also includes an MCU for processing the information from the AFE. This design is a smaller form factor than TIDA-00010.

Features
  • Supports peripheral oxygen saturation measurement
  • Features AFE4403 and third party optical sensore module for measuring oxygen saturation
  • MSP430F5528 MCU for holding algorithm for each measurement
  • This design is tested and provides everything you need to complete your design including schematics, layout, gerber files, and BOM

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
