Tool/software:

Hi, i´m looking for PSPICE models for the OPA1633. We are using LTSpice and it´s realy urgently. Many thanks for your effort.

    Hello Andreas,

    We cannot directly use or support LTSpice simulations as the simulator is owned/maintained by our competitor.  However, I can provide support for PSPICE, PSPICE for TI, and TINA-TI simulators.

    We do have an existing TINA-TI Reference Circuit for OPA1633; this circuit contains the OPA1633 amplifier and the SPICE information can be found by 'right clicking' on the amplifier and selecting 'Enter Macro'.  You can then copy this information into a file and save as a PSPICE '.lib' file.  

    Here is a link to prior e2e support for using TI models in LTSpice: https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1034332/pga281-ltspice-simulation-error

    I went through the process for taking TINA-TI models and creating PSPICE files, which I am attaching here:

    Best,

    Hello Alec, please Inned your help again. I want to use the TSpice model for the OPA552, JFE150 and JFE2140. I make no fould and create for the OPA552 a new symbol with the right PINs from the OPA55x.lib But i get the error: Number of notes does not match pin (8) of sub-circuit "OPA55x". No change. I have the same problems with JFE150 und JFE2140. It would be great if you can help me. Many many thanks. BR Andy

    Hello Andy,

    The OPA552 only has six modeled pins in SPICE; you can view the OPA552 SPICE model in TINA-TI as I described to you above.  Please make sure you are considering the number of inputs/outputs when you define a SPICE model and SPICE model footprint/symbol.

    Overall I would advise you to either use PSPICE, PSPICE-for-TI, and/or TINA-TI if you want to quickly verify model performance.  If you need these models to work in LTSpice, you may need to seek help from the LTSpice support team on importing third-party models using SPICE syntax.

    Best,

    Alec
