Hello,
If we change the RCL value, is the AC characteristics (GBW or Phase margine etc..) varied?
Our customer faced the output oscillation when they change the RCL value of OPA561.
Please see the following as the test conditions. I'm checking the other informtion to customer but I couldn't get.
Case 1 : RCL=39kohm, any Iout, no oscillation
Case 2 : RCL=4.3kohm, Iout= ~ 10mA , no oscillation
Case 3 : RCL=4.3kohm, Iout = 100mA~ , 10MHz, 200mVpp oscillation
Best Regards,
