Tool/software:
Hi TI,
I use LM2904V to design a high side current sense circuit.
I hand made a circuit and measure it, but output voltage is abnormal at Vbat lower than 12V as table below.
I would like to know why, which feature of OPA cause this?
Another question, why I can't use V+ lower than IN+? It also cause abnormal output voltage.
