DESCRIPTION

The TDA9201 is a wide band video amplifier in-

tended for high resolution monochrome or color

monitors.

The BRIGHTNESS and CONTRAST are DC con-

trolled.

The brightness loop includes a comparator gated

by an internally generated pulse.

Thanks to the contrast pre-adjust pin, this device is

well suited for color application too.

The output stage structure (A class current output),

allows to use a very cheap high voltage amplifier

using only one transistor.

This advanced information on a ne w product now in de velopment or undergoing evaluation. Details are sub ject to ch ange without notice.
