Part Number: OPT3101ESTIMATOR-SW Other Parts Discussed in Thread: OPT3101 , OPT3101EVM Hi experts,
Now I'm trying OPT3101 estimator but I can't get the same results as one in the datasheet, page106.
Distance noise is about 2 times worse than the…
Part Number: OPT3101ESTIMATOR-SW Other Parts Discussed in Thread: OPT3101 Hello,
I have been following the example described in the OPT3101 datasheet (document SBAS883A) : section 8 Application and Implementation. I used the OPT3101 system estimator tool…
Hi Stefan,
After calibration, what is the amplitude with the photodiode covered? The uncorrected non-zero amplitude after calibration is considered as residue crosstalk and it is crucial to determine the absolute accuracy of the system.
As distance increases…
Hi Mark,
To my knowledge we do not have a spice model for the OPT3101. However, t he OPT3101 estimator tool can help with selecting optical emitters and photodiodes and estimating performance, range, and accuracy for these components:

Pengsheng,
Have you put these parts into the system estimator to see what it tells you? Are you using any lens' on the photodiode?

Meiling,
You indicate that you only use TX0. In order to get distances up to 10000mm you will need Super HDR and all 4 currents. This will require calibration of all 4 currents in order to get accuracy to the required distance. Use the System Estimator…
Hello,
Our system estimator tool, which can be found at the link below is good for estimating the type of performance you can expect with our OPT3101. With the requirements provided and typical system specs such as target reflectivity percentage, LED…
Hi Tomoya,
You can certainly extend the range by switching from LED to laser. Eye safety will also be a concern that should be checked. Performance can be measured using our system estimator tool http://www.ti.com/tool/OPT3101ESTIMATOR-SW
In addition the…
Hi Amy,
This is not a matter of calibration but signal received by the device. Using black material will reflect less light so if the amplitude value is very low then this is the reason for the error. Changing optics for more output power or narrower…
