Re: use of INA169 High-side current sense on dual polarity power
Nope, it won't work. The INA169 is designed strictly for high-side current. The output comes through an NPN transistor that gets its power from the high side of the sense resistor, so running it on the low side wouldn't give you enough headroom to make it work.
The INA212 is a high/low sensor from the same general family though:http://www.mouser.com/ProductDetail/Tex ... bNztSgM%3d
When you void a product warranty, you give up your right to sue the manufacturer if something goes wrong and accept full responsibility for whatever happens next. And then you truly own the product.
