Hi,
We are using OPA4170 based control circuit in one of the design. When probed on the pins of OPA4170, I am observing unexpected voltages.
The schematic is attached herewith. With the input to the U22.12 through voltage divider circuit as 0V, I am observing the following voltages.
U22.1 = 1.27V
U22.2 = 0.448V
U22.3 = 0.406V
U22.5 = 1.393V
U22.6 = 0.216V
U22.7 = 11.97V
U22.12 = 2.4V
U22.13 = 3.5V
U22.14 = 0V
Can you please identify where is the issue?
Thanks,
Dixit
