I have LTC2992 schematics that I have created completely suitable for the datasheet. I am reading current and voltage on 8 different channels using 4 different LTC2992, but I can't read any current in only one of the lines. However, when I draw current in a controlled manner from this line that I cannot read, I see a proportional current change in a different channel of a different ltc2992 IC. Could this problem be caused by noise? What should I check?, thanks. I am feeding the circuit with 3.3V from VDD input.

Hello.
Please give us more information about your design. The schematic of your design would help a lot.

 

Don't take this the wrong way, but my first instinct is user error or wiring/construction error.
