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.
