DESCRIPTION

The TDA9210 is an I2C Bus controlled RGB pre-

amplifier designed for Monitor applications, 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.

(Plastic Package)

ORDER CODE: TDA9210

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 TDA9210 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 TDA9210

one of the best choice for any CRT Monitor in the

14” to 17” range.

Perfectly matched with the ST Video Amplifiers

TDA9535/36, these 2 products offer a complete

solution for high performance and cost-optimized

Video Board Application.
