1 / 20 page OBSOLETE LM1279 www.ti.com SNOS020B – SEPTEMBER 1998 – REVISED APRIL 2013 LM1279 110 MHz RGB Video Amplifier System with OSD Check for Samples: LM1279 1 FEATURES DESCRIPTION The LM1279 is a full featured and low cost video 2 • Three Wideband Video Amplifiers 110 MHz @ amplifier with OSD (On Screen Display). 8V operation −3dB (4 VPP Output) for low power and increased reliability. Supplied in a • OSD Signal to Any OSD Input Pin 20-pin DIP package, accommodating very compact Automatically Switches All 3 Outputs to the designs of the video channel requiring OSD. All video OSD Mode functions controlled by 0V to 4V high impedance DC inputs. This provides easy interfacing to 5V DACs • Fast OSD Switching Time, Typically 5 ns used in computer controlled systems and digital • 3.5 kV ESD Protection alignment systems. Unique OSD switching, no OSD • Fixed Cutoff Level Typically Set to 1.35V switching signal required. An OSD signal at any OSD input typically switches the LM1279 to the OSD mode • 0V to 4V, High Impedance DC Contrast Control within 5 ns. Ideal video amplifier for the low cost OSD with Over 40 dB Range monitor with resolutions up to 1280 x 1024. The • 0V to 4V, High Impedance DC Drive Control (0 LM1279 provides superior protection against ESD. dB to −12 dB Range) Excellent alternative for the MC13282 in new designs. • 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 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
