LM1279AN 80mA Triple 110MHz PDIP-20 Video Amplifiers

Description

LM1279AN 80mA Triple 110MHz PDIP-20 Video Amplifiers The LM1279AN 80 mA Triple 110 MHz PDIP-20 Video Amplifiers is a highly integrated video preamplifier designed for demanding analog video applications where wide bandwidth and on-screen display (OSD) capability are needed. Packaged in a 20-pin through-hole PDIP, this device contains three independent wideband video amplifier channels, each capable of driving up to 28 mA of output current with a −3 dB bandwidth of 110 MHz, facilitating high-fidelity signal conditioning in RGB video systems. Features Three wideband video amplifiers 110 MHz @ −3dB (4VPP 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 The fixed cutoff level is 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 the LM2407 CRT driver Specifications: Parameter Value Number of Channels 3 Bandwidth 110MHz Supply Voltage 7.5Vto8.5V Current Supply 80mA Output Current per Channel 28mA Operating Temperature (Min) 0°C Operating Temperature (Max) 70°C Package Type PDIP-20 Mounting Type Through Hole Foot print: Symbol: Applications High-resolution RGB CRT monitors Video AGC amplifiers Wideband amplifiers with contrast and drive controls Interface amplifiers for LCD or CCD systems Datasheet: LM1279
