Is there an RC Filter present in the input of the ADS1293EVM? If so, can you point it to me out in the schematic?

In the following thread Alexander Smith says to use the "RC filter from the ADS1298EVM" in his fourth reply

Hi,

There is no RC filter on ADS1293EVM.

Yes, you can find RC filter on ADS1298(R)EVM

Some customers need it and some may not; and customer might need to tune those RC values based on their products, systems designs and/or electrodes, cables, etc.

Thanks.
