ICL5101
Functional Description
THD Adujstment
Introduction:
In order to provide an excellent THD result, the THD of the ICL5101 is adjustable. Especially at high line input
voltage and low load condition, the THD is a critical value. It doesn´t matter in which condition:
- Line input voltage
- Stable load
- Load variation
the ICL5101 is providing best results for all cases – only by trimming a resistor R3 see Figure 18.
