Hello Bonnie,
The PCB is powered by 5V from USB (Laptop).
For debugging, i was driving 100 kOhms resistors.
I have found that there is an oscillation (about 1MHz - hundred of millivolts pic to pic) on the output PIN of the REF2925. It stabilise…
Hi Pete,
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…

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?
Secondary,
For driving a high-power IGBT safely, there…
