LM1203 RGB Video Amplifier System
January 1996
LM1203 RGB Video Amplifier System
General Description
The LM1203 is a wideband video amplifier system intended
for high resolution RGB color monitor applications In addi-
tion to three matched video amplifiers the LM1203 contains
three gated differential input black level clamp comparators
for brightness control and three matched attenuator circuits
for contrast control Each video amplifier contains a gain set
or ‘‘Drive’’ node for setting maximum system gain (Av
e
4
to 10) as well as providing trim capability The LM1203 also
contains a voltage reference for the video inputs For high
resolution monochrome monitor applications see the
LM1201 Video Amplifier System datasheet
