Note
1:
R
LAD
(R

+ R
G
in Figure 4-1) connects V
REF
, V
OUT
and the inverting input of the internal amplifier. The MCP6S22 has
V
REF
tied internally to V
SS
, so V
SS
is coupled to the internal amplifier and the PSRR spec describes PSRR+ only. We
recommend the MCP6S22’s V
SS
pin be tied directly to ground to avoid noise problems.
2:

Q
includes current in R
LAD
(typically 60 μA at V
OUT
= 0.3V). Both I
Q
and I
Q_SHDN
exclude digital switching currents.
3:
The output goes Hi-Z and the registers reset to their defaults; see Section 5.4, “Power-On Reset”.
