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.

PDxB:PDxA = ‘01’ (5),

VOUT not connected

Note 2

This parameter is ensured by characterization.

Note 4

Supply current is independent of current through the resistor ladder in mode VRxB:VRxA = ‘10’.

Note 5

The PDxB:PDxA = ‘01’, ‘10’, and ‘11’ configurations should have the same current.

Note 6

By design, this is the worst-case current mode.
