QFN Package
Single Supply RGB Video Amplier
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 amplier 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.
Amplier A1 is used in a positive gain conguration.
The feedback resistor R8 is 255Ω. The gain resistor
is created from the parallel combination of R6 and R7,
giving a Thevenin equivalent 63.5Ω connected to 3.75V.
This gives an AC gain of + 5 from the noninverting input
of amplier A1 to the cathode of D2. However, the video
input is also attenuated before arriving at A1’s positive
input. Assuming a 75Ω source impedance for the signal
driving VIN, the Thevenin equivalent signal arriving at A1’s
positive input is 3V + 0.4VIN, with a source impedance
of 714Ω. The combination of these two inputs gives an
output at the cathode of D2 of 2 VIN with no additional
DC offset. The 75Ω back termination resistor R9 halves
the signal again such that VOUT equals a buffered ver-
sion of VIN.
It is important to note that the 4.7μF 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 other-
wise turn off. This means that this circuit works ne for
continuous video input, but will require that C1 charge
up after a period of inactivity at the input.
