Single Supply RGB Video Amplifier
The LT1395 can be used with a single supply voltage of
6V or more to drive ground-referenced RGB video. In
Figure 6, two 1N4148 diodes D1 and D2 have been placed
in series with the output of the LT1395 amplifier A1 but
within the feedback loop formed by resistor R8. These
diodes effectively level-shift A1’s output downward by 2
diodes, allowing the circuit output to swing to ground.
Amplifier A1 is used in a positive gain configuration. The
feedback resistor R8 is 255
. The gain resistor is cre-
ated from the parallel combination of R6 and R7, giving
a Thevenin equivalent 63.5
connected to 3.75V. This
gives an AC gain of +5 from the noninverting input of
amplifier A1 to the cathode of D2. However, the video
input is also attenuated before arriving at A1’s positive

input. Assuming a 75
source impedance for the signal
driving V
IN
, the Thevenin equivalent signal arriving at
A1’s positive input is 3V + 0.4V
IN
, with a source imped-
ance of 714
. The combination of these two inputs gives
an output at the cathode of D2 of 2 V
IN
with no additional
DC offset. The 75
back termination resistor R9 halves
the signal again such that V

equals a buffered version
of V
IN
.
It is important to note that the 4.7
μ
F capacitor C1 has
been added to provide enough current to maintain the
voltage drop across diodes D1 and D2 when the circuit
output drops low enough that the diodes might otherwise
turn off. This means that this circuit works fine for
continuous video input, but will require that C1 charge up
after a period of inactivity at the input.
