1. Ci was shorted for any common-mode input voltage measurement. All other measurements were taken with CI = 0.1μF (unless otherwise noted).

2. Cs1 = 0.1 μF is placed very close to the device. The optional Cs2 = 10 μF is used for datasheet graphs.

3. The 30 kHz low-pass filter is required even if the analyzer has an internal low-pass filter. An RC low-pass filter (1 kΩ, 4700pF) is used on each

output for the data sheet graphs.
