General Description
The LM1205/LM1207is avery high frequency video amplifi- system intendedforusein high resolution RGB monitor
applications.In additiontothe three matched video amplifi-
ers,the LM1205/LM1207 contains three gated single end- input black level clamp comparatorsfor brightness con-
trol, three matchedDC controlled attenuatorsfor contrast
control, and threeDC controlled sub-contrast attenuators
providing gaintrim capabilityfor white balance.AllDC con-
trol inputs offer high input impedance andan operation
range from0Vto4Vfor easy interfacetobus controlled
alignment systems. The LM1205/LM1207 also containsa
blanking circuit which clampsthe video output voltagedur-
ing blankingto within 0.1V above ground. This featurepro-
vides blanking capabilityatthe cathodesof theCRT.A spot
killeris provided forCRT phosphor protection during power-
down.
Features Three wideband video amplifiers 130 MHz (LM1205)@
