Current stability
The figure below shows the current stability over 1 hour of a CTL20-2-200 controller operated at 200 mA.
The figure below shows the Allan deviation of CTL20 controllers operated at their rated current.
Current noise
The figure below shows the current noise of CTL20-2 controllers. The CTL20-2-200 current is measured at 200 mA across a 10 Ω load, and the CTL20-2-100 at 100 mA across a 20 Ω load.
Temperature stability
The figure below shows the relative variation of the output current against the ambient temperature for CTL20 controllers operating at their rated current.
