Part Number: OPT3101EVM
Other Parts Discussed in Thread: OPT3101

Dear Technical Support Team,

I'd like to know general spec of OPT3101EVM.

①How is the FOV?

②How is the max / min distance?

OPT3101 datasheet shows up to 15m, however I think that distance and FOV depend on the lens mounted on EVM.

③How is the operation temperature of EVM?

→EVM has temp sensor and it calibrate itself.

However EVM user guide doesn't have the operation temperature.

Best Regards,

Hello ttd,

I wanted to let you know that the device expert is currently out of office and will return by the end of this week.

Hi,

Please refer here e2e.ti.com/.../724400

What temperature range are you trying to use the EVM at?

Best,

Alex

Hi Alex,

Thank you for your reply.
I don't decide the temperature range for application.
For example, broadcom ToF module has temperature range from -20℃ to 70℃.

This is ToF module and it fixed the specification like FOV and distance etc.

OPT3101EVM is evaluation board and optical is mounted. so I'd like to know the general specification(distance and FOV) if you have experimental result with EVM.

Best Regards,

Hi ttd,

The EVM temp rating will be determined by the LED on the board if the duty cycle on the LED is not changed. Please refer to the SFH4550 datasheet for the requirements. If you lower the duty cycle of the device on the LED then the temperature can be increased. Also if you operate at a less then full scale current the temperature rating is higher. dammedia.osram.info/.../SFH 4550.pdf

Assuming the LED spec is not violated then the EVM can function up to the chip spec.

Best,

Alex
