In the ADI datasheet in the input pins of the modulator (CAPLN & CAPLP) there are 3 capacitors: an 1nF between them and two 100pF on each pin tied to gnd. In other application board focused on ADI DSP (Blackfin or others) that use the AD1871 as A/D converter, I noticed that these 3 capacitor for each input are different in value from what suggested in datasheet of AD1871. Usualy there are two 1nF (or 10nf) to GND and a 100pF between this pins. Is there someone that can clarify about this.
Thank you
