OPERATION AS A VIDEO LINE DRIVER
The AD811 has been designed to offer outstanding performance
at closed-loop gains of +1 or greater, while driving multiple
reverse-terminated video loads. The lowest differential gain and
phase errors are obtained when using ±15 V power supplies.
With ±12 V supplies, there is an insignificant increase in these
errors and a slight improvement in gain flatness. Due to power
dissipation considerations, ±12 V supplies are recommended
for optimum video performance. Excellent performance can be
achieved at much lower supplies as well.
The closed-loop gain versus the frequency at different supply
voltages is shown in Figure 42. Figure 43 is an oscilloscope
photograph of an AD811 line driver’s pulse response with
±15 V supplies. The differential gain and phase error versus the
supply are plotted in Figure 44 and Figure 45, respectively.
Another important consideration when driving multiple cables
is the high frequency isolation between the outputs of the
cables. Due to its low output impedance, the AD811 achieves
better than 40 dB of output-to-output isolation at 5 MHz
driving back-terminated 75 cables.
