This is a very interesting fact that you have brought up. It appears that the REF2925 ocsillation is causing higher currents in the OPA4209. This is possible.
I was examing your circuit diagram and noticed that the by pass capacitor on the…
Sorry for the late reply. I still tested the circuit with supplies +/- 5V but I grounded the Ref pin, one more thing I changed the gain of INA to 10, which I saw in datasheet it will give better common mode range vs output.
The results is right…
Other Parts Discussed in Thread: ISO5500EVM , REF2925 Hello,
Does any one has built this IGBT gate driver circuit?
How do I do using the iso5500EVM to drive single 100A, 1200V IR or Ixys IGBT?
For driving a high-power IGBT safely, there is a…
