LM1279
110 MHz RGB Video Amplifier System with OSD
General Description
The LM1279 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 LM1279 to the OSD mode within 5 ns. Ideal
video amplifier for the low cost OSD monitor with resolutions
up to 1280 x 1024. The LM1279 provides superior protection
against ESD. Excellent alternative for the MC13282 in new
designs.
