Part Number: LMH7322
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hi,

my customer is currently doing a design with the LMH7322. For simulation purposes the downladed the Pspice model, imported it into the simulation tool and launched a simulation. But as soon as the simulation it launched an error pops up. The customer suspects something might be wrong with a subcircuit (AND-gate).

Attached is the model they are using for simulation. Could you please take a look.

regards,

Hi Stani,

One of our team will take a look. FYI, most likely it will be next week before he can respond due to holidays in US (thanksgiving holidays).

Hi Arash,

to you have an update for me. the customer can't move forward with his design since he can't simulate. He is reaching out on a daily basis.
thank you.

Hi Stani,

Would you provide answers to the following questions?

1, What is the simulation tool?
2, What kind of simulation was run (attach a schematic if possible)?
3, What was the error message the customer got?

Thanks,
JC

Hi JC,

here is the reply i got from the customer:
1) OrCad/PSpice (Version V16.6)
2) Here is the schematics: www.ti.com/.../getliterature.tsp
3) AND-Gate doesn't have termination of the subcircuit (translated from German to englisch)

note the the schematics was downloaded from ti.com. He tried simulation without modifying anything and got that error.

Regards,
Stani

Hi JC,
happy to hear you could replicate the issue.
Please let me know when the fix is done so that i can inform the customer to download the latest model. He needs it to move forward with his project.

Best regards
Stani

Stani,

Sorry about the delay. I was able to duplicate the issue in SPB_17.2. We will fix this shortly.

Thanks,
