CHARACTERISTICS
† Notice:
Stresses above those listed under “Absolute
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 operational listings of this specification is not
implied. Exposure to maximum rating conditions for extended
periods may affect device reliability.

The MCP6275’s V
CM
for op amp B (pins V
OUTA
/V
INB
+ and V
INB
–) is V
SS
+ 100 mV.
The current at the MCP6275’s V
INB
– pin is specified by I
B
only.
This specification does not apply to the MCP6275’s V
OUTA
/V
INB
+ pin.
The MCP6275’s V
INB
– pin (op amp B) has a common mode input voltage range (V
CMR
) of V
SS
+ 100 mV to
V
DD
– 100 mV. CMRR is not measured for op amp B of the MCP6275. The MCP6275’s V
OUTA
/V
INB
+ pin (op amp B)
has a voltage range specified by V
OH
and V
OL
.
Set by design and characterization.
Does not apply to op amp B of the MCP6275.
