TPA6211A2 simulation model

Other Parts Discussed in Thread: LM7322, LM4991

Sorry if I am so late, I had to finish other tasks before getting back to this simulation.
I have tried the suggested model (new, empty file, just your model a power and signal source), but something is going wrong:

Circuit: * E:\Documenti\LTspiceXVII\lib\sym\AutoGenerated\Draft1.asc

ERROR: Node U1:I0:I0:I21:1:102 is floating and connected to current source G:U1:I0:I0:I21:1:RA

Direct Newton iteration for .op point succeeded.


I will let you know if I success with this model.

Regards, Roberto

PS: I have tried with other models with no issues, for example LM7322.

    Hi Roberto,

    I split your post into a new thread since this is no longer related to LM4991.

    I can take a look at the messages you've got, but it seems you tried this in LTSpice, are you having the same results on PSpice?

    Hi Roberto,

    It has been some time since last communication: Are you still having troubles simulating this device? Were you able to simulate on PSpice instead?

    I'am sorry, I think I have yet too much software, I'have tryied only in LTSpice, but I can't run this simulation. Other models from TI runs smoothly, I can't catch the difference. At last I have used a generic (single) opamp connected as balanced output. 

    Anyway, thank you very much, regards,

    Roberto
