Integrated Circuit
RGB Video Amplifier System
Description:
The NTE7081 is a wideband video amplifier system in a 28–Lead 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 “Drive” 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.
Features:
D Three Wideband Video Amplifiers (70MHz @ –3dB)
D Inherently Matched (±0.5dB) Attenuators for Contrast Control
D Three Externally Gated Comparators for Brightness Control
D Provisions for Independent Gain Control (Drive) of each Video Amplifier
D Video Input Voltage Reference
D Low Impedance Output Driver
