Part Number: TINA-TI
Other Parts Discussed in Thread: THS4541,

Hello,

My customer is trying to simulate THS4541 by using LT-Spice.
When they download spice model from following URL, however they got following error.

URL : https://www.ti.com/jp/lit/zip/sbom906
Error : 

ERROR: Node U3:I0:I19:1:102 is floating and connected to current source G:U3:I0:I19:1:RA

ERROR: Node U3:I0:I19:1:302 is floating and connected to current source G:U3:I0:I19:1:RC

ERROR: Node U3:I0:I21:1:102 is floating and connected to current source G:U3:I0:I21:1:RA

If you have updated model which fix this issue or any solution to avoid this, could you please share it to me ?

Best Regards,

    Hi Ryuuichi,

    There is an instructional video for how to import a TINA-TI model into a generic spice simulator, like LTSpice (linked here).

    However, at TI we are unable to provide tested models or support debugging LTSpice software. Our best recommendation is to take the PSPICE model and import the netlist into LTSPICE: this does not always create a complete working model but may work well enough for evaluation. Linked is another E2E thread that explains this in a little more detail (here).

    Thanks,

    Nick
