Hi,

I want to design power monitoring with reference to P2597_B04_OrCAD schematic. Why are resistors R163, R151 and R141 (680K) used? Do I need to use it?

Secondly, why are the capacitances C99, C89, and C78 used as 4.7uF? In the INA3221 datasheet, this value is suggested as 0.1uF - 1uF. Do you mind if I use 1uF?

Third, why are the IN+ and IN- pins drawn at 90 ohms? Is it possible to draw at other impedance values?

Hi, we don’t have guide on power monitor design. If you want to use it same as devkit, then you need to copy the full design.
