This reference design demonstrates the analog capabilities of the MSPM0L1306 in a low-cost, single chip pulse oximeter design. The operational amplifiers within the MSPM0L1306 serve as the transimpedance amplifier and current control driver with zero-drift, low-noise capabilities. The integrated high-speed, analog-to-digital converter (ADC) provides the ability to oversample and achieve high levels of dynamic range. This design features a GUI to visualize photoplethysmography (PPG) waveforms and vitals measurements of heart rate in beats per minute (BPM) and peripheral oxygen saturation (%SpO2).
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
