Can we get 4 different frequencies analog outputs simultaneously from AD8403 IC

Hello,

I am using AD8403 for Analog output. I want to get 4 different frequencies analog outputs simultaneously from that IC. Is it possible? please let me know

    Hi Thippeswamy,

    Happy New Year!

    By analog output do you mean that you want to use it as a DAC?

    If so, you can not achieve true simultaneous update of all 4 wiper position. You can try using higher SPI speeds so that it seems like a simultaneous update based on your application. But i am not sure if it will work if your application is a high speed operation.
