Output noise: For voltage-source, within the range from no-load to maximum load
[Vp-p]
For current-source, at following load [Ap-p]
Switching noise:
Settling Time
The time to reach ±0.1% the final value when varying the output from zero to full-scale.
Setting conditions: Source values and limiter values are full-scale settings.
Load conditions: Resistive load and 200 pF max. load capacitance
