Overview
a
2.
7 V to 5.
5 V RGB-to-NTSC/PAL Encoder with Load Detect and Input Termination Switch AD723
or combined for composite video (CV).
All outputs are available separately and optimized for driving 75 Ω loads.
Active termination is used for lower power consumption.
A smart load detect feature powers down unused outputs and can be used to monitor the continuing presence or absence of an external TV.
This enables plug-and-play operation.
In addition, a logic controlled triple switch at the input solves the applications problem of differing load conditions when an RGB monitor is disconnected.
When an RGB monitor is not present, the R, G, and B terminations are enabled by the user.
