Hi Eric,

Thanks for your post!

I'm checking with the designer on this one, however it may take an extra day to get a response.

I think that Figure 48. is incorrect since it doesn't correspond to the paragraph above, figure 47. or figure 49.

I will let you know once this has been confirmed!

Hi Eric,

The configuration in Figure 47. is correct. I have made a note to have the datasheet revised.

Thanks for bringing this to our attention and have a good day!
