Simulation tool
OPT3101 system estimator tool

The OPT3101 system estimator tool analyzes the performance of the OPT3101, which is a time-of-flight (ToF)-based, long-range proximity and distance sensor analog front end (AFE). The tool determines if the OPT3101 is able to meet design requirements under various conditions.

Calculation tool
OPT3006 Field of View (FoV) Simulator
The field of view simulator allows users to understand the potential effects of changing the angle of exposure such as the the amount of light taken in and the performance thereafter.
IDE, configuration, compiler or debugger
OPT3101 configurator tool

The OPT3101 time-of-flight (ToF) analog front end (AFE) configurator tool is an offline graphical user interface (GUI) for customizing the configuration of the OPT3101, which is a ToF-based, long-range proximity and distance sensor AFE. OPT3101CONFIG-SW provides a high level of (...)
