Original question:

OPA1611: OPA1611

OPA1611: Spice model

Part Number: OPA1611

Tool/software:

Where can I find a downloadable spice model of OPA1611/12 for simulation? I'm unable to find it on the product page. I used to be able to download models easily, now your website makes it impossible...why is this so difficult to find/access? Can I get a speedy response?

    The Spice model is shown in the link below. 

    I do not know what you are referring to. The reference design and Spice model are intended to be user friendly, and we do not attempt to make the process harder for user to access these models. You do need to be registered user in order to access these.

    For your convince, I download the OPA161X PSpice model for you, see the attachment below.

    Thanks for the quick reply, and glad it works from your end. I used to be able to access this just like you showed, but despite resetting my browser, clearing everything, for some reason TI thinks I'm not on a desktop...makes no sense and no other website has this issue. See screenshot below. Please advise what to do. Extremely strange. Thanks for any assistance you can provide.

    Hi Kapila,

    We use google as search engine and browser, and I am unable to say about other browser.

    The TI website does have certain built in protection against unfriendly, illegal access or phishing. But it should not prevent the customer to download the required file from the normal access. Anyway, if you have further problem, please send a query, and we are happy to resolve it for you. 

    Best,

    Raymond
