Hello,

 

My name is Meir and I am DFAE in Israel.

 

One of my customers use the AD7626 for military imaging application.

 

Please see attached the waveforms of the convert clock: blue and yellow and analog input: red.

Please see also attached the part of schematic of ADC.

 

The problem that they see is a noise on analog side also between rise and fall.

 

Can you please advise what is the possible reason for this noise?

 

Thanks a lot,

Meir
