SLOS652A –DECEMBER 2009–REVISED JUNE 2010
TEST SETUP FOR GRAPHS
1. C
I
was shorted for any common-mode input voltage measurement. All other measurements were taken with C
I
= 0.1-mF
(unless otherwise noted).
2. C
S1
= 0.1mF is placed very close to the device. The optional C
S2
= 10mF 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 (1kΩ,
4700pF) is used on each output for the data sheet graphs.
