Here is my complete Schematic for ADS1298, please tell me weather this is correct or any kind of limitation were there.

here is my Front end anti-aliasing Filter having cutt off of 5.12khz which give enough attenuation at Fmod=512khz.

Here is schematic of ADS1298/ADS1198

And here is power supply design

please give me soon review.

Hi Ahmed,

I think the schematic looks generally ok. One thing that I do not see is the placement of decoupling capacitors on the supply pins. This is helpful to improve noise performance. Also, you probably do not need to have inductors in series with the LDO outputs. This can possibly cause issues if you place them before the output load capacitors.

Regards,

Is this work well with ADS1198 if we use same circuit.

Yes, ADS1298 and ADS1198 are pin-to-pin compatible.
