3V/5V, 6dB Video Amplifiers with High Output-Current Capability
General DescriptionThe MAX9504A/MAX9504B 3V/5V, ground-sensing
amplifiers with a fixed gain of 6dB provide high output
current while consuming only 10nA of current in shut-
down mode. The MAX9504A/MAX9504B are ideal for
amplifying DC-coupled video inputs from current digi-
tal-to-analog converters (DACs). The output can drive
two DC-coupled 150Ωback-terminated video loads in
portable media players, security cameras, and automo-
tive video applications. The MAX9504B features an
internal 160mV input offset to prevent output sync tip
clipping when the input signal is close to ground.
The MAX9504A/MAX9504B have -3dB large-signal
bandwidth of 42MHz and -3dB small-signal bandwidth
of 47MHz.
The MAX9504A/MAX9504B operate from a single +2.7V
to +5.5V supply and consume only 5mA of supply cur-
rent. The low-power shutdown mode reduces supply
current to 10nA, making the MAX9504A/MAX9504B ideal
for low-voltage, battery-powered video applications.
The MAX9504A/MAX9504B are available in tiny 6-pin
µDFN (2mm x 2mm) and 6-pin SOT23 packages, and
are specified over the -40°C to +85°C extended tem-
perature range.

Detailed DescriptionThe MAX9504A/MAX9504B 3V/5V, 6dB video amplifiers
with low-power shutdown mode accept DC-coupled
inputs and drive up to two DC-coupled, 150Ωback-ter-
minated video loads. The MAX9504B provides an inter-
nal input offset voltage of 160mV, which allows
DC-coupled input signals down to ground without clip-
ping the output sync tip.
The MAX9504A/MAX9504B operate from a single +2.7V
to +5.5V supply and consume only 5mA of supply cur-
rent. The low-power shutdown mode reduces supply cur-
rent to less than 1µA, making the MAX9504A/MAX9504B
ideal for low-voltage, battery-powered video applications.
Output Current CapabilityAs shown in the Typical Application Circuit, the
MAX9504A/MAX9504B can drive up to two 150Ωloads
to ground at the same time because the outputs can
source guaranteed 45mA (min) current. Two 150Ωloads
to ground is the same as a single 75Ωload to ground.
Since the MAX9504A/MAX9504B can also sink guaran-
teed 40mA (min) current, they can also drive two, AC-cou-
pled 150Ωloads. When VCC> 3V, the output can swing
2.4VP-P. When VCC> 4.5V, the output can swing 2.8VP-P.
Input Offset (MAX9504B)The MAX9504A/MAX9504B amplify DC-coupled video
signals with a gain of +2V/V (+6dB). The MAX9504B
features a 160mV input offset voltage (VOS) that allows
a video signal input range to ground without clipping
the output sync tip. The MAX9504B output voltage is
the sum of the input voltage and the input offset voltage
gained up by a factor of 2.
VOUT= 2 x (VIN+ VOS)
For example, if VIN= 1V and VOS= 0.16V then:
VOUT= 2 x (1V + 0.16V) = 2.32V
Shutdown ModeThe MAX9504A/MAX9504B feature a low-power shut-
down mode (ISHDN< 1µA) for battery-powered/
portable applications. Driving SHDNhigh enables the
output. Driving SHDNlow disables the output and
places the MAX9504A/MAX9504B into a low-power
shutdown mode. In shutdown, the output resistance is
4kΩ(typ) due to the combination of feedback resistors
from OUT to ground with FB connected to OUT.

Applications Information
Using the MAX9504A/MAX9504B
with Video Current DACs
Video current DACs source current into a resistor con-
nected to ground. The output voltage range for com-
posite video and luma (Y) is usually from ground up to
1V (see Figure1). Notice that the sync tip is quite close
to ground. Standard single-supply amplifiers with rail-
to-rail outputs have difficulty amplifying input signals at
or near ground because their output stages enter a
nonlinear mode of operation when the output is pulled
close to ground.
The MAX9504B level shifts the input signal up by
160mV so that the output has a positive DC offset of
320mV. As a result, the MAX9504B output stage always
operates in the linear mode. Even if the input signal is
at ground, the MAX9504B output is at 320mV.
At the output of a video current DAC, the blank level of
the chroma signal is usually between 500mV to 650mV.
The voltage swing above and below the blank level is
approximately ±350mV (see Figure1). If the blank level
is 550mV, then the lowest voltage for the chroma signal
is 200mV. For the case of chroma signals, no input
level shift is needed because 200mV gained up by two
is 400mV, which is well within the linear output range of
the MAX9504A or MAX9504B. Since the MAX9504A
does not have an input level shift, the MAX9504A
should be used with chroma signals. In summary, use
the MAX9504B with composite video and luma signals
from a DAC, and use the MAX9504A with chroma sig-
nals from a DAC.
Using the MAX9504A/MAX9504B with a
Video Reconstruction Filter
In most video applications, the video signal generated
from the DAC requires a reconstruction filter to smooth
out the steps and reduce the spikes. The MAX9504 has
a high-impedance, DC-coupled input that can be con-
nected directly to the reconstruction filter.
For standard-definition video, the video passband is
approximately 6MHz, and the DAC sampling clock is
27MHz. Normally, a 9MHz lowpass filter can be used
for the reconstruction filter. This section demonstrates
the methods to build simple 2nd- and 3rd-order pas-
sive Butterworth lowpass filters with 9MHz cutoff fre-
quency. See Figures 2 and 3.
