Monolithic Triple 5.5 ns High Gain CRT Driver
General DescriptionThe LM2465isan integrated high voltage CRT driver circuit
designed for usein color monitor applications. TheIC
contains three high input impedance, wide band amplifiers
which directly drive the RGB cathodesofa CRT. Each
channel hasits gain internallysetto −20 and can drive CRT
capacitive loadsas wellas resistive loads presentin other
applications, limited onlybythe package’s power dissipation.
TheICis packagedinan industry standard 9-lead TO-220
molded plastic package.
Features Higher gainto match LM126X CMOS preamplifiers0Vto 3.75V input range Stable with 0–20pF capacitive loads and inductive
peaking networks Same pinoutas LM2467/8/9, maintaining the standard
LM243X Family pinoutfor easy PCB layout Convenient TO-220 staggered lead package style
Applications Upto 1280x 1024at 75Hz Pixel clock frequenciesupto 135 MHz Monitors using video blanking
