Note

The MCP6285’s VCM for op amp B (pins VOUTA/VINB+ and VINB–) is VSS + 100 mV.

The current at the MCP6285’s VINB– pin is specified by IB only.

This specification does not apply to the MCP6285’s VOUTA/VINB+ pin.

The MCP6285’s VINB– pin (op amp B) has a common mode range (VCMR) of VSS + 100 mV to VDD – 100 mV.

The MCP6285’s VOUTA/VINB+ pin (op amp B) has a voltage range specified by VOH and VOL.
