DC CHARACTERISTICS (CONTINUED)

DC Characteristics

Standard Operating Conditions (unless otherwise specified):

Operating Temperature: -40°C

 TA  +125°C (Extended)

Unless otherwise noted, all parameters apply across these specified operating ranges:

VDD = +2.7V to 5.5V, VREF = +2.048V to VDD, VSS = 0V

Gx = ‘0’, RL = 5 k from VOUT to VSS, CL = 100 pF

Typical specifications represent values for VDD = 5.5V, TA = +25°C.

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 (MCP48FVBX2), this is the effective resistance of the each resistor ladder.

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

Note 11

Variation of one output voltage to mean output voltage.
