Other Parts Discussed in Thread: TIDA-00313, ISO1541
I would like to use the INA231 to measure current on a -5.8V rail.
I have read through TIDA-00313 and come up with the following circuit.
Could someone please take a look over to see if it looks fine.
Any comment are welcome.
IRz (current throyugh Rz) is approximately 11.3mA
SDA (10K) pullup 0.5mA
SCL (10K) Pullup 0.5mA
Rz = |-5.8-)-4.7)|/11.3mA = 97 (use 81)
