SINGLE SUPPLY VIDEO LINE DRIVER
The EL8100, EL8101 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 31 is the single supply non-inverting
video line driver configuration and Figure 32 is the inverting
video ling driver configuration. The signal is AC coupled by
C
1
. R
1
and R

are used to level shift the input and output to
provide the largest output swing. R

and R
G
set the AC gain.
C

isolates the virtual ground potential. R
T
and R
3
are the
termination resistors for the line. C
1
, C
2
and C
3
are selected
big enough to minimize the droop of the luminance signal.
