In the AD7194 datasheet on page 52 is stated that:
"Connect an R-C filter to each analog input pin to provide rejection at the modulator sampling frequency. A 100 Ω resistor in series with each analog input, a 0.1 μF capacitor between the analog input pins, and a 0.01 μF capacitor from each analog input to AGND are advised."
I don't understand the role of this 0.1 uF cap between adjacent channels.
Can someone help?
