I'm planning to use a multiplying DAC e.g. AD5443 configured to provide a unipolar output and attenuate a Vref of 1MHz. Looking at the datasheet, the device bandwidth of 12MHz suggests that will be a phase shift between Vref and the output. I would like the output signal phase to be fixed and not change with code (amplitude) changes. Do you think I could achieve a phase stability better than 1 degree? If not is there a way to improve it or an alternative device to use?
