The MAX9509/MAX9510 Functional Diagram/Typical
Application Circuit includes a 75Ω back-termination
resistor that limits short-circuit current if an external short
is applied to the video output. The MAX9509/MAX9510
also feature internal output short-circuit protection to
prevent device damage in prototyping and applications
where the amplifier output can be directly shorted.
The MAX9509/MAX9510 feature a low-power shutdown
mode for battery-powered/portable applications.
Shutdown reduces the quiescent current to less than
10nA. Connecting SHDN to ground (GND) disables the
output and places the MAX9509/MAX9510 into a low-
power shutdown mode. In shutdown mode, the sync-tip
clamp, filter (MAX9509), amplifier, charge pump, and
linear regulator are turned off and the video output is
high impedance.
The quiescent power consumption and average power
consumption of the MAX9509/MAX9510 are remarkably
low because of 1.8V operation and DirectDrive technolo-
gy. Quiescent power consumption is defined when the
MAX9509/MAX9510 are operating without load. In this
case, the MAX9509/MAX9510 consume approximately
5.8mW. Average power consumption, which is defined
when the MAX9509/MAX9510 drive a 150Ω load to
ground with a 50% flat field, is about 11.7mW. Table 1
shows the power consumption with different video sig-
nals. The supply voltage is 1.8V. OUT drives a 150Ω
load to ground.
Table 1. Power Consumption of MAX9509/
MAX9510 with Different Video Signals
Notice that the two extremes in power consumption occur
with a video signal that is all black and a video signal that
is all white. The power consumption with 75% color bars
and 50% flat field lies in between the extremes.

Devices designed to generate 1V
the output of the video DAC can still work with the
MAX9509/MAX9510. Most video DACs source current
into a ground-referenced resistor, which converts the
current into a voltage. Figure 3 shows a video DAC that
creates a video signal from 0 to 1V across a 150Ω
resistor. The following video filter amplifier has a gain of
2V/V so that the output is 2V
The MAX9509/MAX9510 expect input signals that are
0.25V
to work with the MAX9509/MAX9510 by scaling down the
150Ω resistor to a 37.5Ω resistor, as shown in Figure 4.
The 37.5Ω resistor is 1/4 the size of the 150Ω resistor,
resulting in a video signal that is 1/4 the amplitude.
Figure 3. The video DAC generates a 1V
150 Ω resistor connected to ground.
Figure 4. The video DAC generates a 0.25V
37.5 Ω resistor connected to ground.
