0.1μF ceramic capacitor in single-supply applications.
This will help prevent thermal noise from the internal
80k
Ω-80kΩ voltage divider (25nV/√Hz) and other exter-
nal sources of noise from being converted to differential
noise due to mismatches in the feedback networks. It is
also recommended that the resistive feedback networks
be comprised of 1% resistors (or better) to enhance the
output common mode rejection. This will also prevent
VOCM input referred common mode noise of the common
mode amplier path (which cannot be ltered) from being
converted to differential noise, degrading the differential
noise performance.
