FEEDBACK_OFFSET transconductance gain annotation #15

Closed dnadlinger closed 4 years ago

dnadlinger commented 4 years ago

According to the schematic, the transconductance from FEEDBACK_OFFSET to the feedback shunt current is 47 mA / V, but it looks like it should be 23.5 mA / V, giving a total range of 0 mA to 48 mA.

I checked the rest of the gain calculations as well, and they are correct (divider ratios are slightly off).

Thanks!

I suspect I changed the sense resistor at some point and forgot to update the annotation.
