DESCRIPTION
The TDA9209 is an I2C Bus controlled RGB pre-
amplifier designed for Monitor application, able to
mix the RGB signals coming from any OSD de-
vice. The usual Contrast, Brightness, Drive and
Cut-Off Controls are provided.
In addition, it includes the following features:
– OSD contrast,
– Bandwidth adjustment,
– Grey background,
– Internal back porch clamping pulse generator.

(Shrink Plastic Package)
ORDER CODE: TDA9209
The RGB incoming signals are amplified and
shaped to drive any commonly used video amplifi-
ers without intermediate follower stages. Even
though encapsulated in a 24-pin package only,
this IC allows any kind of CRT Cathode coupling :
– AC coupling with DC restore,
– DC coupling with Feed-back from Cathodes,
– DC coupling with Cut-Off controls of the Video
amplifier (ST Amplifiers TDA9533/9530).
As for any ST Video pre-amplifier, the TDA9209 is
able to drive a real load without any external inter-
face.
One of the main advantages of ST devices is their
ability to sink and source currents while most of
the devices from our competitors have problems
to sink large currents.
These driving capabilities combined with an origi-
nal output stage structure suppress any static cur-
rent on the output pins and therefore reduce dra-
matically the power dissipation of the device.
Extensive integration combined with high perform-
ance and advanced features make the TDA9209
one of the best choice for any CRT Monitor in the
14” to 17” range.
Perfectly matched with the ST Video Amplifiers
TDA9530/33, these 2 products offer a complete
solution for high performance and cost-optimized
Video Board Application.
