SINGLE SUPPLY VIDEO LINE DRIVER
The EL8202, EL8203 and EL8403 are wideband rail-to-rail
output op amplifiers with large output current, excellent dG,
dP, and low distortion that allow them to drive video signals
in low supply applications. Figure 36 is the single supply
non-inverting video line driver configuration and Figure 37 is
the inverting video ling driver configuration. The signal is AC
coupled by C1. R1 and R2 are used to level shift the input
and output to provide the largest output swing. RF and RG
set the AC gain. C2 isolates the virtual ground potential. RT
and R3 are the termination resistors for the line. C1, C2 and
C3 are selected big enough to minimize the droop of the
luminance signal.
