Part Number: OPT4048 Tool/software: I am evaluating the use of the OPT4048 for a color detection application where a strip of paper will be illuminated with a white LED and the OPT4048 will then generate a color reading.
This application does not have…
Hello Daniel,
Sorry for the late reply, unfortunately I had an urgent trip abroad and did not deal with this topic.
You are absolutely right, it was the algorithm I was using that had an error.
Thank you very much for your help.
Kind regards,

Part Number: OPT4048 Tool/software: Hi,
We want to use multiple OPT4048's to check the color correctness of LED-traffic lights during pre-production testing. I can see not only a spread between the individual OPT4048 x/y coords, but also a significant…
Part Number: OPT4048 Tool/software: Hi ti team,
1. It is impossible to operate the register. Even if writing is repeated multiple times, the value read from the register is still always a default value (attempts have been made for the two registers 0A…
Part Number: OPT4048 Other Parts Discussed in Thread: OPT4060 Tool/software: Good day,
I have a OPT4060 EVM and would like to know if the OPT4048 will be work correctly if I plug it into the OPT4060 EVM?
Or is each EVM only intended for a specific variant…
Part Number: OPT4048 Dear, the chip can trig measurement via Hardware trigger and Register trigger in one-shot mode .I see ,an I2C write to the M register triggers a measurement in Register trigger way. But I can't find M register in the datasheet. Could…
Hi Roger,
In terms of CCT (formula I used for CCT is below), there is a 9% difference between the 4048 and the color meter.
n = (CIEx-0.3320)/(0.1858-CIEy); CCT = 437*n^3 + 3601*n^2 + 6861*n + 5517
Whether or not this is in the normal range depends on…
Part Number: OPT4048
Tool/software:
I'm using the OPT4048 light sensor to measure the qualities of a sample while a light is being shined on it. I believe the values are fluctuating due to the timing of the PWM signals. If I look strictly at the CCT…
