| |
Diagnostic Function - Open and short Output Detection (OOD & OSD) via Sout
 |
White Balance - Each Single channel can be corrected. The Data Latch is responsible for each Dot correction
 |
Brightness Control - The regulated current sources are designed to provide a constant current, which is adjustable through one external resistor.
