NTE7120
Integrated Circuit
3 Channel Video Amp for
High Resolution Color TV
Description:
The NTE7120 is a semiconductor integrated circuit in a 30鈥揕ead DIP type package that has a built鈥搃n
3鈥揷hannel amplifier with 50MHz band. Every channel is provided with a broad鈥揵and amplifier, main/
sub contrast control, main/sub luminance (brightness) control, peaking, blanking, and peak limiter
functions. Accordingly, this device is designed for use in high鈥搑esolution color display monitors.
Features:
D
The employment of a new bi鈥損olar wafer process makes it possible to reduce power dissipation,
and 3 channels can be incorporated in this amplifier (V

D
Main and sub contrast and luminance controls are provided; the main control can change contrast
and luminance at the same time for 3 channels, and the sub control can change them independently
for each channel.
D
The DC feedback circuit built in the IC can produce a stable DC level at the IC output pins.
Applications:
