Part Number: OPT4001 Hi,
I have a question regarding CRC calculation. Registers 0 and 1 have the following content:
Reg0 = 0x 080B
Reg1 = 0x 801B
I calculated Mantissa which results: 0x80B80
Furthermore I calculated X[3] (as it is the easiest): X[3] =…

Part Number: OPT4001 Hi team,
I have several questions about OPT4001.
How to understand "Semi-logarithmic output with 9 binary logarithmic full-scale light range and highly linear response within a range"
What's the meaning of this picture?…
Part Number: OPT4001 Other Parts Discussed in Thread: , OPT3004 Hi Experts,
Good day.
Customer is designing a sensor using multiple OPT4001 chips. They have purchased the OPT4001EVM to explore this sensor, but would like to know if it is possible to order…
Part Number: OPT4001 We have been working with the OPT4001 sensor for many months, and something that seems to repeatedly happen is that the I2C communication will simply stop working. The device is getting the proper power, but when attempting to communicate…
Part Number: OPT4001 I have read the user manual for the OPT4001EVM and the datasheet for the OPT4001 and am having a hard time figuring out how to implement the CRC check in code. Is there an example or a more detailed explanation for this?
Part Number: OPT4001 Hello,
I have read through all of the available documentation and am only able to find the overall dimensions of the chip, but no information about the size and location of the pads for the chip, making it very hard to design a PCB…
Part Number: OPT4001 When using a constant current LED source in conjunction with the OPT4001EVM, I am able to get excellent readings over I2C using an Arduino.
However, when I turn this LED off, and have the OPT4001EVM set up in a dark enclosure, I…
