Note 1

This parameter is ensured by design.

Note 2

This parameter is ensured by characterization.

Note 7

Resistance is defined as the resistance between the VREF pin (mode VRxB:VRxA = ‘10’) to VSS pin. For

dual-channel devices (MCP47FVBX2), this is the effective resistance of the each resistor ladder. The

resistance measurement is of the two resistor ladders measured in parallel.

Note 12

Variation of one output voltage to mean output voltage.
