VOUT SETTLING TIMING

Timing

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 = +1.8V to 5.5V, VSS = 0V

RL = 5 k from VOUT to VSS, CL = 100 pF

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