Part Number: LM2904
Dear Expert
We use LM2904DR as voltage sampling .But we found in some of batch that it's would make the output reverse ?
Below is abnormal waveform:channel 2 is output ,channel 4 is input+ ,and channel 3 is input-
Below is sch
It's should be a positive output ,but output a negetive lever and only few batch could be cause that problem.
