TPA6211A1-Q1 Pspice model

Other Parts Discussed in Thread: TPA6211A1-Q1, TINA-TI

Hi expert,

My customer is using TPA6211A1-Q1 Pspice model in LTspice tool. They transferred the pspice model to LTspice model, but it doesn't work in LTspice. Do you have some solutions for this?

Thanks!

Hi Ethan,

Do you know if customer had any specific error when trying to use unencrypted Pspice model into LTspice?

hi expert

i use pspice model to auto generate .asy file to simulate in LTspice, But it indicate error:

ERROR: Node U1:I0:I0:I21:1:102 is floating and connected to current source G:U1:I0:I0:I21:1:RA
ERROR: Node U1:I0:I0:I19:1:102 is floating and connected to current source G:U1:I0:I0:I19:1:RA

Hi, Thanks for the additional information. I'll take a look at the model and check if it needs any update or fix, although we're not supporting LTspice as this is third party software.

Hi, I don't have LTspice to try this out, but you can do it on your side:

It seems you can add some large resistors on the nodes having this error, you may find this previous thread useful: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/844373/ths4541-the-pspice-model-for-ths4541-dose-not-work/3156315#3156315

Otherwise, you can always use TINA-TI or PSpice for TI to simulate our unencrypted model, it is working correctly on these platforms.
