† Notice: Stresses above those listed under "Maximum
Ratings" may cause permanent damage to the device. This is
a stress rating only and functional operation of the device at
those or any other conditions above those indicated in the
operation listings of this specification is not implied. Exposure
to maximum rating conditions for extended periods may affect
device reliability.

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.

(typically 60 µA at V

= 0.3V). Both I

exclude digital switching currents.
3: The output goes Hi-Z and the registers reset to their defaults; see Section 5.4, “Power-On Reset”.
