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,
   
Features
■ Three wideband video amplifiers 110 MHz @ −3dB (4
    VPP output)
■ OSD signal to any OSD input pin automatically switches
    all 3 outputs to the OSD mode
■ Fast OSD switching time, typically 5 ns
■ 3.5 kV ESD protection
■ Fixed cutoff level typically set to 1.35V
■ 0V to 4V, high impedance DC contrast control with over
    40 dB range
■ 0V to 4V, high impedance DC drive control (0 dB to
    −12 dB range)
■ Matched (±0.3 dB or 3.5%) attenuators for contrast
    control
■ Output stage directly drives CRT drivers
■ Ideal combination with LM2407 CRT driver
   
Applications
■ High resolution RGB CRT monitors
■ Video AGC amplifiers
■ Wideband amplifiers with contrast and drive controls
■ Interface amplifiers for LCD or CCD systems
