† 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

operational listings of this specification is not implied.

Exposure to maximum rating conditions for extended periods

may affect device reliability.

Note

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 range (VCMR) of VSS + 100 mV to VDD – 100 mV.

The MCP6275’s VOUTA/VINB+ pin (op amp B) has a voltage range specified by VOH and VOL.
