Hi,

does anyone has experience with p-p noise of ADS1298? In datasheet I found 4uV p-p, and this is quite lot for EEG. Is there any information I've missed?

Thanks,

Mirko,

The noise performance of the ADS1298 will depend on several factors.. These include reference voltage, PGA gain, data rate, and high-resolution/low-power modes. However, all of these are covered in the datasheet in Tables 1 through 4.

Joseph,

given that theoretical minimum is 2.4uV, it is likely that 4uV estimation is quite real. Our application requires <2.2 uV, so we will wait for next generation of this circuit.

Thanks,

Mirko
