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 = +2.048V to VDD, VSS = 0V, Gx = 0, RL = 5 k from VOUT to GND, CL = 100 pF.

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

LSb

VRnB:VRnA = 10, Gx = 0, Gx = 1,

VREF = VDD/2, VREF = VDD,

VDD = 2.7-5.5V, no load

See Section 2.0 “Typical

LSb

VRnB:VRnA = 10, Gx = 0, Gx = 1,

VREF = VDD/2, VREF = VDD,

VDD = 2.7-5.5V, no load

See Section 2.0 “Typical

LSb

VRnB:VRnA = 00, Gx = 0,

VREF = VDD = 2.7-5.5V, no load

Note 1:

This parameter is ensured by characterization.

INL and DNL are measured at VOUT with VRL = VDD (VRnB:VRnA = 00).

10: Code range is dependent on resolution: 8-bit, codes 6 to 250; 10-bit, codes 25 to 1000; 12-bit,

100 to 4000.
