I am using the DAC53004 to limit the current in a H-Bridge. The VOUT of the DAC (OUTA and OUTB) are connected to the gates of the MOSFETs and the FB (FBA and FBB) are connected to the sources.
I measured the differential voltage between E1 and E2 and I observed an "under-shoot". The red arrow is when the OUT of the DAC are enabled.
To see if the problem was coming from my circuit or from the DAC, I removed the DAC from the circuit and I connected OUT to FB directly.
This is the result:
Any reason why the DAC would do that?
Thanks for your help.
