Notes:
1. Minimum R1 resistance should be calculated based on LED forward voltage, maximum LED current, LED voltage rail
used, and maximum active TXO voltage.
2. When using LEDs near the min and max wavelength limits, higher radiant intensities may be needed to achieve the
system's proximity sensing performance goals.
