LT1806/LT1807
Single Supply Video Line Driver
The LT1806/LT1807 are wideband rail-to-rail op amps with
large output current that allows them to drive video signals
in low supply applications. Figure 4 depicts a single supply
video line driver with AC coupling to minimize the quies-
cent power dissipation. Resistors R1 and R2 are used to
level-shift the input and output to provide the largest signal
swing. The gain of 2 is set up with R3 and R4 to restore
the signal at V

the signal that comes from the load. The input termination
resistor, R
the incoming line is necessary. The values of C1, C2 and
C3 are selected to minimize the droop of the luminance
signal. In some less stringent requirements, the value of
capacitors could be reduced. The –3dB bandwidth of the
driver is about 90MHz on 5V supply, and the amount of
peaking will vary upon the value of capacitor C4.
