Other Parts Discussed in Thread: INA181,
Hi,
On the third page of the TIDA-010015 schematic I see a 10Ohm resistor in series with a 0.5mOhm sense resistor. There is another 10Ohm on the IN- input. The problem is that the best 10Ohm resistor has 0.5% error, which is 50mOhm or 100 times above the sense resistor value. Wouldn't that cause sensing issues? The INA181 datasheet shows there is no need for input resistors on IN+ and IN- so can they be omitted?
Please help me answer these questions:
- Will resistors 66 and 78 on TIDA-010015 schematic cause sensing errors?
- What are these resistors protecting INA181 against?
- Can these resistors be omitted?
Thank you for your help,
Arthur
