AD9284 - Can i swap positive and negative pin of one of the ADC block?


I am using AD9284 dual ADC in conjunction with driver ADA4937-2 for one of the IQ receiver. I am facing difficulty in routing the outputs of driver to the ADC deferentially without changing the layer. Is it recommended to swap the inputs of one of the ADC?

  • Hi Mahesh,

    Swapping the input polarity on one channel of the ADC will effectively flip the phase of the output on that channel, as compared to the other ADC channel. If you are counting on your two Analog inputs remaining in-phase with each other its best to drive the ADC inputs symmetrically.

    Best Regards,
