Hello,

I have tried to finize the my design on ADS1298/ADS1294R; I have two questions though.

1. Is it necessary to pull up the the three active low pins to DVDD through 10K or 100K resisters CS, RESET, PWDN ?

2. Does DDRY pin needs to be pulled high through a resistor?

Thank you!!

Hello Mes,

Thanks for your post. I hope you are doing well!

1) Yes, I would tie these pins high.
2) No, the DRDY pin signals that new data is ready therefor it may not be wise to always have it pulled high.
