描述 Description

General Description
The LM1208/LM1209 is a very high frequency video amplifier system intended for use in high resolution RGB monitor applications. In addition to the three matched video amplifiers, the LM1208/LM1209 contains three gated single ended input black level clamp comparators for brightness control, three matched DC controlled attenuators for contrast control, and three DC controlled drive attenuators providing independent full range gain control in each channel for wide range white balance.

特性 Features

■ Three wideband video amplifiers 130 MHz @ b3 dB
?? (4 VPP output)
■ Matched (±0.1 dB or 1.2%) attenuators for contrast
?? control
■ Three externally gated single ended input comparators
?? for cutoff and brightness control
■ 0V to 4V, high input impedance DC contrast control
?? (40 dB range)
■ 0V to 4V, high input impedance DC full range gain
?? control (Drive) for each video channel (40 dB range)
■ Spot killer, blanks outputs when VCC < 10.6V
■ Capable of 7 VPP output swing (slight reduction in
?? bandwidth)
■ Output stage blanking
■ Output stage directly drives most hybrid or discrete
?? CRT drivers
