Single Supply Video Line Driver

The LT1806 is a wideband rail-to-rail op amp with high

output current that allows it to drive video signals in low

supply applications. The figure on the front page depicts

a single supply video line driver with AC coupling to

minimize the quiescent power dissipation. Resistors R1

and R2 are used to level-shift the input and output to

provide the largest signal swing. The gain of two is set up

attenuated by 6dB due to the matching of the 75

Ω line with

the back-terminated resistor, R5. The back termination

will eliminate any reflection of the signal that comes from

it is used only if matching of the incoming line is neces-

sary. 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.
