NE5539 COLOR VIDEO AMPLIFIER
The NE5539 wideband operational amplifier is easily adapted for
use as a color video amplifier. A typical circuit is shown in Figure 7
along with vector-scope1 photographs showing the amplifier
differential gain and phase response to a standard five-step
modulated staircase linearity signal (Figures 8, 9 and 10). As can be
seen in Figure 9, the gain varies less than 0.5% from the bottom to
the top of the staircase. The maximum differential phase shown in
Figure 10 is approximately +0.1 .
The amplifier circuit was optimized for a 75
termination impedance with a gain of approximately 10 (20 dB).
