Dear Team
Here is Kevin from Delta Taiwan team
I would like to propose OPA2607 to replace MAX4128
Customer is calculating the GBW for the PFC current sense circuit.
Vth is the OP input from the shunt resistor, which is 100kHz sine wave
Can you help me to check is customer calculating the GBW correct?

Hello Kevin,
Can you provide more context here? Is customer trying to find the minimum GBWP needed for the amplifier to achieve a 100kHz signal?
Once comment I have in regards to the GEA(s) equation is that the input capacitance of the amplifier can be added for more accuracy.
Best,
