DESCRIPTION
The TDA9201isa wide band video amplifier in-
tended for high resolution monochromeor color
monitors.
The BRIGHTNESS and CONTRAST are DC con-
trolled.
The brightness loop includesa comparator gatedan internallygenerated pulse.
Thanksto thecontrast pre-adjust pin,this deviceis
well suitedfor color application too.
The outputstage structure(A class currentoutput),
allowsto usea very cheap high voltage amplifier
using only one transistor.
