Hi Champs,

what should the power pad be connected to? GND? Is there a recommendation?

Power pad of INA333 should be connected to a negative supply. This means that in the single supply application it should be connected to ground but for dual supply the power pad should be tied to a negative rail.

Hi Simon,

Thanks for your post, I can help you.

This part should always have thermal pad soldered to the pcb, and it should be tied electrically to the negative rail.

Hope that helps!

Thanks a lot Tamara!

Is this documented somewhere? I could not find it in the datasheet.

Hi Simon,

This isn't documented in the datasheet. We will need to add this.
