TINA/Spice/DAC0800: Spice model for legacy devices

Dominic Heaton

Part Number: DAC0800
Other Parts Discussed in Thread: TINA-TI, , DAC8820

Tool/software: TINA-TI or Spice Models

I need to simulate a circuit in spice which contains the DAC08 at the centre of it. It is a legacy circuit - I am not looking to use the latest components rather the ones that exist in the circuit already. I really need a spice model for the DAC08, DAC0800 or an equivalent IC recommendation that matches these as closely as possible

Dominic,

Unfortunately SPICE models for DACs, and data-converters at large, historically haven't been as wide-spread as those of operational amplifiers and other components. There's been some investment here and there from TI and others for DAC SPICE models, but at present we only have what is posted here: www.ti.com/.../spice-models.html

We are working on a new DAC SPICE macro-model, but it is not ready at this time.

What specifically are you investigating which requires a SPICE model? Perhaps we can find other means to assist you.

Hi Dominic,

Welcome to E2E and thank you for your query. You can look at the Tina model of DAC8820. This is the closest available match.

Hope that answers your question.

Im trying to import the DAC8820 PSpice library file to see if it will be sufficient but I am just getting an empty library whenever I try the normal .olb generation process normally used to import these files. I can import the .lib file into the pspice simulation configuration folder but currently I cannot get a component symbol or orcad to recognize the olb. I can see the model is encrypted but I assume I should still be able to import the library.

Dominic,

Please try the attached un-encrypted PSPICE model.

Thanks I can now simulate using the DAC8820 model
