What does the "functional operating" voltage mean for the VL6180X

EPere · ‎2018-12-18

In Section 5 of the datasheet for the VL6180X you are presented with Normal Operating conditions.

It lists that the optimum voltage range [2.7,2.9] and the functional range [2.6,3.0].

What exactly does the functional range mean ? If I am 3.1V or 3.3V, will the device not work ?

What is the difference between functional and optimum ?

You will get the best performance if you hit 2.8 volts exactly. We did all our testing and meet the requirements in the data sheet between 2.6 and 3.0. If you go over 3.0 the chip will not work well at all.

Overvoltage is not a good thing here.
