描述 Description

General Description
The LM1202 is a very high frequency video amplifier system intended for use in high resolution monochrome or RGB color monitor applications. In addition to the wideband video amplifier the LM1202 contains a gated differential input black level clamp comparator for brightness control, a DC controlled attenuator for contrast control and a DC controlled sub contrast attenuator for drive control.

特性 Features

■ Wideband video amplifier
   (f-3dB = 230 MHz at VO = 4 VPP)
■ tr, tf = 1.5 ns at VO = 4 VPP
■ Externally gated comparator for brightness control
■ 0V to 4V high input impedance DC contrast control
   (40 dB range)
■ 0V to 4V high input impedance DC drive control
   (±3 dB range)
■ Easy to parallel three LM1202s for optimum color
   tracking in RGB systems
■ Output stage clamps to 0.65V and provides up to 9V
   output voltage swing
■ Output stage directly drives most hybrid or discrete
