AD9850 Balanced Filter

Question asked by chrisjn52 on Jul 29, 2018

I have a requirement for a DDS with a output sine wave bandwidth of 10Hz to 10MHz with a balanced output centred at 0V when using +3V3 & -3V3 supplies. I am using a AD9850 and a transformer is usually recommended but impractical for the frequency range I require. Are there any benefits to using a differential quantisation filter on the two outputs of the AD9850 as opposed to a single-ended filter that is usually recommended?
