    Hi all,

    I am using the OPA337PA op-amp in a simulation circuit. When running the simulation, I am having the attached errors. Why is this happening please?

    When I replaced the OPA337PA with the OPA340PA the errors did not occur. What is the main difference between these two ICs?

    Thanks in advance.

    The simulator was unable to resolve all of the related calculations within the specified iterations to within the specified tolerances.

    Changing your simulation accuracy/speed/convergence/iterations parameters should help.

    You can also try using the Transient Simulation options of "Start external DC supply voltages at 0V" or "Skip initial operating point solution".
