DAC8812: Spice model for DAC8812 and DAC8830

Part Number: DAC8812
Other Parts Discussed in Thread: DAC8830, DAC8831, DAC8822, TINA-TI

Dear Sir

We are currently using the DAC8812 in our design.  Due to supply chain issues, we are in the process of going to the DAC8830.  We are in the semi industry and as a consequence, we are required to validate the new design in many different ways.  One of these ways are SPICE simulation.  Do you have the SPICE models for the DAC8812 and DAC8830?  Thank you.  

  • Hi Dennis,

    Both the DAC8830 (DAC8831) and DAC8812 (DAC8822) have models in our TINA-TI spice tool.  I recommend using those as a starting point for simulation.  It might be possible to export the model into your tool of choice as well.

    Thanks,

    Paul

  • Dear Mr. Frost

    Thank you for your help.  I noticed that the DAC8830 (DAC8831) data sheet and the DAC8822 data sheet have Burr-Brown references and the DAC8812 data sheet does not.  Since Burr-Brown was acquired some time ago by TI, are these DACs legacy parts?  I, what is their projected EOL?  How comparable are the DAC8812 and DAC8822?  When I read the two data sheets, the output specifications looked very similar.  Are the two topologies the same?  I intended to do a noise analysis comparison between the DAC8830 and DAC8812 in the simulation.  Will the DAC8831 and DAC8822 simulation return the same results?  

  • These devices were developed by the original folks within Burr-Brown after the TI acquisition.  We still maintain the BB brand on some of our devices.  These device are a bit older, but they are well supported and are still very popular.  There is no planned EOL for these, and we strive to support them forever Slight smile

    The difference between the DAC8812 and DAC8822 is the SPI/parallel interface.  The resistor ladders are the same and you would expect the same noise.  Our expectation is that the DAC8831 and DAC8822 TINA models will have the same result.

    Thanks,

    Paul

  • Again, thank you for your support.
