DC CHARACTERISTICS (CONTINUED)

Standard Operating Conditions (unless otherwise specified):

Operating Temperature: -40°C

 TA  +125°C (Extended)

All parameters apply across the specified operating ranges unless noted.

VDD = +2.7V to 5.5V, VREF = +1.000V to VDD, VSS =0V, RL =2 k from VOUT to GND, CL = 100 pF.

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

PDxB:PDxA = 01(5), VRxB:VRxA = 10,

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.
