... LM2466 Monolithic Triple 7.5 ns CRT Driver General Description The LM2466 is an integrated high voltage CRT driver circuit designed for use in color monitor applications. The IC con- tains three high input impedance, wide band amplifiers which directly drive the RGB cathodes of a CRT. Each channel has its gain internally set to − ...

... Note load includes parasitic capacitance. Figure 2 shows a typical test circuit for evaluation of the LM2466. This circuit is designed to allow testing of the LM2466 in a 50Ω environment without the use of an expensive FET probe. The two 2490Ω resistors form a 200:1 divider with the 50Ω resistor and the oscilloscope. A test point is included for easy use of an oscilloscope probe. The compensation capacitor is used to compensate the stray capacitance of the two 2490Ω ...

... This example assumes a capacitive load and no resistive load. TYPICAL APPLICATION A typical application of the LM2466 is shown in Figure 11 and Figure 12. Used in conjunction with an LM1267, a complete video channel from monitor input to CRT cathode can be achieved. Performance is ideal for 1024 x 768 resolution displays with pixel clock frequencies MHz ...
