Hi Team,

May I ask for a PSpice model of DAC8812?

Regards,

    Hi,

    As of now we don't have any spice models for DAC8812. We are in the process of developing spice models for DAC our portfolio.

    We have models for voltage output DAC as of now, current output DAC models are in pipeline.

    May I know what kind of application you are targeting with DAC8812? I can help you with schematics review and architecture reviews.

    Regards,

    AK

    Hi AK,

    Thank you for your quick response.

    The customer is planning to use it for a Digital to Synchro converter where a 4 quadrant DAC is required to scale the reference voltage input. 

    A reference supply 26V rms 400Hz comes in to the circuit, and they need to separately scale 3 outputs, in phase and in antiphase to the reference.

    The output will be 11.8V rms. The microcontroller will set the scaling values over an SPI link.

    I have requested a schematic diagram and block diagram to understand the application better.

    Regards,

    Danilo

    Hi,

    I have understood the application. Send us the schematics and I will review the same.

    Hi,

    The schematics for the DAC section looks fine to me. I didn't see any bypass capacitor for VDD in the schematics, probably you may have it in another sheet.

    Do you need any other help?
