NTE7081
Integrated Circuit
RGB Video Amplifier System
Description:
The NTE7081 is a wideband video amplifier system in a 28鈥揕ead DIP type package intended for high
resolution RGB color monitor applications. In addition to three matched video amplifiers, the
NTE7081 contains three gated differential input black level clamp comparators for brightness control
and three matched attenuator circuits for contrast control. Each video amplifier contains a gain set
or 鈥淒rive鈥?node for setting maximum system gain (A
V
= 4 to 10) as well as providing trim capability.
The NTE7081 also contains a voltage reference for the video inputs.
