LMH32401: LMH32401 simulation

Part Number: LMH32401
Other Parts Discussed in Thread: TINA-TI


I have struggled a lot getting the simulation for the LMH32401 to work.


I think that the symbol on the schematic package extracts the pin names in a different order as to the simulation model. 

From the library part I can see this sequence (* LMH32401 - Rev. A)


however the  netlist generated from the schematic is:

X_U1         I_IN P3_3 0 VOD VOCM AMB_CNCL GAIN N00322 N00318 LMH32401


 The figure shows how I think the sequence is. (unfortunately I cannot load the figure)

This way I can get results thats almost believable, although output does not track V0cm.

Can you please confirm if this is the correct way to use the simulation model?


  • Hello AJ,

      Thank you for bringing this issue to our attention. You are correct, it looks like this was fixed in version B of the PSpice For TI model and Tina TI model:

    1. Incorrect PSpice for TI Symbol (Rev A  on LMH32401 product folder and in PSpice for TI Library)

    2. Correct PSpice for TI Symbol (Rev B, only located on LMH32401 product folder)

    3. Correct Tina-TI Model (LMH32401 product folder)

    I will have to work with the simulation team to fix this model within PSpice for TI. It will release as an update to the software. In the meantime, please use LMH32401 for PSpice Library (Rev. B) found under Design & Development tab located in the LMH32401 product folder: link. I have attached the zip folder below as well. Sorry for the inconvenience and thank you for pointing this issue out to us.

    Thank you,
