Other Parts Discussed in Thread: ADS1292R, ADS1291, ADS1292
The datasheets for ADS1291 (and the rest of the series) are a bit inconsistent in regards to bypassing recommendations. The texts says "Each ADS1291, ADS1292, and ADS1292R supply should be bypassed with 10-μF and a 0.1-μF solid ceramic capacitors." The schematic shows 1uF and 0.1uF. The EVK also uses 1uF and 0.1uF.
Question 1: Which is correct? Should the larger capacitor be 1uF or 10uF?
Question 2: What is the impedance this is trying to achieve? Which frequency ranges are important? Could you draw a curve of impedance vs frequency and say "any bypass that provides this impedance or lower would be okay"?
Question 3: Does it matter what size these are? (0603, 0402, ...) What type? (X7R, etc)
