Beanfly-

Sounds like a cool project! Thanks for your email -I’ll get back to you shortly.

Ah, so you're auto-switching between two shunt resistors (or shorting one of them). Makes sense and means the worst case burden point is 75mV right at 1mA before the switching happens. The auto-switching function wasn't clear to me; I assumed I was forced to setup one or the other (to avoid the brownout issue as you mention.)

My apologies: I was reading the spec sheet on my mini iPad and must have misread the higher range as 150mV/mA rather than 150mV/A, so the off-by-1000 error was my own.  :-+
