LM1279A
110 MHz RGB Video Amplifier System with OSD
General Description
The LM1279A is a full featured and low cost video amplifier
with OSD (On Screen Display). 8V operation for low power
and increased reliability. Supplied in a 20-pin DIP package,
accommodating very compact designs of the video channel
requiring OSD. All video functions controlled by 0V to 4V
high impedance DC inputs. This provides easy interfacing to
5V DACs used in computer controlled systems and digital
alignment systems. Unique OSD switching, no OSD switch-
ing signal required. An OSD signal at any OSD input typically
switches the LM1279A to the OSD mode within 5 ns. Ideal
video amplifier for the low cost OSD monitor with resolutions
up to 1024 x 768. The LM1279A provides superior protection
against ESD. Excellent alternative for the MC13282 in new
designs.
Features
n Three wideband video amplifiers 110 MHz @ 3dB (4
V
PP output)
n OSD signal to any OSD input pin automatically switches
all 3 outputs to the OSD mode
n Fast OSD switching time, typically 5 ns
n 3.5 kV ESD protection
n Fixed cutoff level typically set to 1.2V
n 0V to 4V, high impedance DC contrast control with over
40 dB range
n 0V to 4V, high impedance DC drive control (0 dB to
12 dB range)
n Matched (±0.1 dB or 1.2%) attenuators for contrast
control
n Output stage directly drives most hybrid or discrete CRT
drivers
Applications
n High resolution RGB CRT monitors
n Video AGC amplifiers
n Wideband amplifiers with contrast and drive controls
n Interface amplifiers for LCD or CCD systems
