THS4531: Error in THS4531 PSpice Model

Part Number: THS4531
Other Parts Discussed in Thread: , THS4551

The PSpice model for the THS4531

http://www.ti.com/product/THS4531/toolssoftware

http://www.ti.com/lit/zip/slom263

is generating an error during simulation. The error is associated from line 116:

E_E5 VREF 0 N3339187 0 1

due to the fact the value VREF is not mentioned anywhere else in this file.

Any resolution on this?

Thanks

- Norman

  • Hey Norman, 

    The original THS4531 model had a lot of problems actually, 

    Most later efforts to improve things focused on the improved DC offset version, the THS4531A and in fact there is a 2018 updated TINA model for that version. 

    I have seen that the recent THS4551 model update missed on the noise terms, not sure about that THS4531A update - but it will likely get you going for now, 

    The A is the same die as the THS4531 so the model file will be applicable.

  • And also Norman, I noticed you said Pspice model, there is also a updated compatible Spice model there, look under design and development tab, down at the bottom of that table of models. If you click on that is expands the directory where you want the .lib file.
