Figure 1. Typical Connection Diagram
GNDA, the negative voltage rail for the R, G and B diodes is not connected internally to GNDD. GNDA should
ideally be connected to the ground of the video DAC IC. This will prevent any ground bounce caused by digital
signals from injecting noise onto the R, G and B signals. Analog GND and digital GND are typically connected
on the printed circuit board.
