  • DAC8803: DAC8803: For 'Analog voltage' output only, what do I do with other pins?

    Resolved
    Part Number: DAC8803 Hello all, I would like to use the DAC8803 to output analog voltage. Looking at the user guide and application note, I see that the Iout and Rfb pins are connected to opamps, but I do not understand why. Can anyone please explain…

  • RE: Product recommendation for generation of waveforms to control a pair of scanning mirrors

    Resolved
    Just an update, in case someone runs into this thread: I bought the DAC8803 EVM and was able to connect it over spi with a STM32F407 (STM32F4 discovery board), and it ran without problems. Thanks for the recommendation, Jim.
