† 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.

Note 1:

The MCP6275’s VCM for op amp B (pins VOUTA/VINB+ and VINB–) is VSS +100 mV.

The current at the MCP6275’s VINB– pin is specified by IB only.

This specification does not apply to the MCP6275’s VOUTA/VINB+ pin.

The MCP6275’s VINB– pin (op amp B) has a common mode input voltage range (VCMR) of VSS + 100 mV to

VDD – 100 mV. CMRR is not measured for op amp B of the MCP6275. The MCP6275’s VOUTA/VINB+ pin (op amp B)

has a voltage range specified by VOH and VOL.

Set by design and characterization.

Does not apply to op amp B of the MCP6275.
