Other Parts Discussed in Thread: OPA228
Tool/software: WEBENCH® Design Tools
Hello dear Support Team,
I have a question regarding the Filter Designer. When I simulate a High Pass Filter(10Hz) with the OPA348, it switches from the OPA348 to OPA228 within the simulation. For each stage, a minimal OpAmp GBWP is calculated. In my case, the min GBWP for the first stage is 520Hz. Then OPA348 would still be sufficient. So my question is, why does Webench switch the Amplifier Models? And how is the min GBWP calculated?
