The datasheet of the AD9954 specifies that DACBP should be decoupled to Ground.
It would make sense to me to decouple
it to the Analog Ground rather than the Digital Ground. It is not specified in
Any more information about this ?
You are correct, the DACBP pin should be decoupled to AGND. We have used a 1uF
capacitor on the AD9954 evaluation board. The schematic of the evaluation board
is available on the AD9954 product page on our website.
