Part Number: AMC1350
Hi
Need clarity regarding the resistor divider network connection at the input of AMC1350. Figure below shows the current schematic for battery voltage sensing.( 0-850). But in our case there is one requirement as protection for battery voltage reversal. That is if the battery is connected reversed, at that time also the battery voltage should be sensed properly. Can you confirm whether this connection is proper or not ?Because while testing we are observing oscillation .Tried to give input at the positive side of resistor network alone, then we did not observe any oscillations , but we give input at the negative side oscillations were there. So i doubt the connection at the input of AMC1350.

Please verify the connection..
