HI there
I'm using the Multisim 14.0.0. There's a 8-pin opa141 available in the library. I wanted to use it for a amplifier, but a simulation error has occured. The report said that 'DC operating point calculation did not converge'.
i had tried using opa 241,opa 4141,they all have this problem,Pspice model error?

DC operating point calculation did not converge
op simulation canceled

Hi..
.. as the OPA141 normally works ...
... most likely OPA141 is unstable at low gain factors ...

in fact,i want to make a high pass filter .but i cannot simulate the bandwidth.
in high gain , DC operating point calculation did not converge neither.
