VEML7700 - Reccomended Voltage & Current

Post by jspr »

Hello Adafruit,

What is the recommended mA (current) for VEML7700 on 3.3V?

What is the recommended mA (current) for VEML7700 on 5V?

I am using the blue model. Thanks!

The datasheet can give you an idea of what the VML7700 chip can draw. It looks like 50mW max. So worst case would be roughly:

10mA @ 5v
15mA @ 3v3

Probably some overhead from the board components, but a decent estimate.

Thank you very much. Would it be different since i am using adafruit veml7700 board ? I figured I’d be different since there are more components on it.

I appreciate the help !

Let me ask my question once more with my correction:

What is the recommended mA (current) for adafruit veml 7700 on 3.3V?

What is the recommended mA (current) for adafruit veml 7700 on 5V?

I don't know the specific full board draw. Just the approximation based on the chip datasheet. You will want to measure yourself if need precision values.
