Can someone tell me the difference between OPT101 and OPT301? As far as I can tell they have the same size photodiode, essentially the same responsivity, and other similarities. OPT101 can take a broader range of power supply inputs, and the OPT301 is in a hardier packaging. Is packaging the only difference? If so, why the large price difference? (Digikey: OPT101P $8.50 vs OPT301M $88.06)
For reference I'm going to be using one of these to determine the HDMI latency of a projector.
Thank you.
