Other Parts Discussed in Thread: TINA-TI
We have designed in the LMP8603 and are currently in developmental test of engineering model units of our PCBs. The LMP8603 circuitry does not seem to be working according to the spec. Below is the photo of how we are using it, which appears to be according to the datasheet. However, current is only being sensed unidirectional.
I expect that when no current is applied, the output should read ~2.5V due to the offset.
Here is what is actually happening. A1/A2 is reading roughly 2.25V, and the output is reading 0.2V when no current is present.
