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.
