Note 1: R
LAD
(R
F
+R
G
in Figure 4-1) connects V
SS
, V
OUT
, and the inverting input of the internal amplifier. Thus, V
SS
is coupled
to the internal amplifier and the PSRR spec describes PSRR+ only. It is recommended that the V
SS
pin be tied directly
to ground to avoid noise problems.

LAD
(typically 0.6 µA at V
