Part Number: ADC12DJ5200RF
Other Parts Discussed in Thread: TPS7A83A

Hi,

In my design, I have 3 ADCs ADC12DJ5200 devices. Please refer the below attached image for power scheme for all the ADCs. I want to confirm that the Power scheme is proper or not, I want to check the LDO part numbers will work with the ADC12DJ5200 adc part.

can anyone review and provide your feedbacks.

    Hello Harshitha,

    All the voltage look correct and your choice of LDOs should work, however I would recommend using the parts suggested in ADC12DJ5200 datasheet. For example the TPS7A83A would be a good choice as it has lower output noise. Additionally it is important to follow the power on sequence detailed below. I hope this helps.

    Best,
