AD2S1200 aliasing

Hello, This AD2S1200 has ADC internal both sin and cos inputs.

As you know, ADC sampling has an aliasing if without low pass filter before input.

Is AD2S1200 also have possible introduce aliasing issue same as other ADC components?

 

If the answer yes, do you have any recommendation about input filter circuit?

I found https://ez.analog.com/message/80674#80674 topic. It is very useful.

But my question point is R+C filter would be required also aliasing or AD2S1200 has a internal filter to remove aliasing already.

 

Thank you for your help in advance.

Best regards,

Sofy
