We are moving towards production of the second version of this device and are looking for input on the schematic. Most of it is standard stuff, but the low noise LED pulsing and reading the intensity is a challenge. We are looking at the ratios of repeated pulses, so absolute accuracy isn't very important. But noise is - we would like to see 15 or 16 bits.
