is there a LMP2014MT spice model?

Other Parts Discussed in Thread: LMP2014MT, LMP2011

Hi

I Could not find a spice model for the LMP2014MT opamp. Is there a spice model for evaluation?

Thanks

Jonathan

  • Hi Johnathan,

    You can use the LMP2011 (single) model.

    The main difference between the 2011 and the 2014 is the 25 vs 30uV max offset and a few mV less swing on the 2014.

    BTW: Read the headers in the SPICE file. You can enable or disable the "chopping" function by commenting out a few lines. The "chopping" function will emulate the effects of the internal chopping circuitry, which will add the input transients and chopper "noise". If you are planning a low noise or high impedance design, be sure to enable this. It does slow down the simulation, though. So you can turn it off for debugging or circuit fine-tuning.

  • I downloaded today snom113.zip. When I tried to open it, Ark archiver display the following error message: ... failed with the following error: The archive reading failed with the following error: Invalid central directory signature.

    This is the first time that I got such kind of error for content downloaded from TI. Please let me know how to proceed.

    Thanks in advance,

  • Hi Dennis,

    I just tried downloading it and it opened fine with Winzip, 7-Zip and the Windows7 native file explorer - so the archive file is fine.

    Ark is a Linux tool. You may not be using the correct command line options to extract (usually need a -x).

    Have a look at the Ark documentation:

  • Oh, that's interesting. I tested it with another application (Archive Manager) and it works! Possibly my Ark setup was confused by zip inside zip. Who knows :) Many thanks for rapid response.

    Best regards,
