Other Parts Discussed in Thread: ADS1299
Hi,
I think I've found a problem with the datasheet of the ADS1299.
In page 4, it states that the test signal's amplitude is +-1mV or +- 2mV.
But then, in page 41 the bit 2 of register Config2 says that the amplitude of the test signal is
(VREFP – VREFN) / 2.4 mV
Which since we are using the internal reference is 4.5V / 2.4 = 1.875 mV.
We have obtained the value with the ADS1299 Kit and we get 6990 with gain 1 so approximately 1.875mV.
So I guess this last value is the correct one.
Is this correct?
Thank you.
