Part Number: INA3221
My customer have design INA3221 in their board, i now just find R/C filter value have some problem(customer use 10ohm & 10 uF).
because i am not familiar this part. may you have other suggestion to us? and if some channel we have no use. may we direct flotation? (or like C3317 connect way?)
What problems are you seeing? I recommend looking over datasheet section 8.4.3 titled “Filtering and Input Considerations” to see if it helps you with your design. The capacitor you are using is outside of the recommended spec, which is to use values from 0.1 µF to 1.0 µF, as shown below.
Also, here is a link to a thread that discusses how to deal with unused channel inputs.
