NTE7120
Integrated Circuit
3 Channel Video Amp for
High Resolution Color TV
Description:
The NTE7120 is a semiconductor integrated circuit in a 30–Lead DIP type package that has a built–in
3–channel amplifier with 50MHz band. Every channel is provided with a broad–band 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–resolution color display monitors.
Features:
D The employment of a new bi–polar wafer process makes it possible to reduce power dissipation,
and 3 channels can be incorporated in this amplifier (V_CC = 12V, I_CC = 77mA)
D Input: 1V_P–P (Typical)
Output: V_P–P (Maximum)
Frequency Band: 50MHz
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:
D CRT Display
