Detailed Description
The MAX9504A/MAX9504B 3V/5V, 6dB video amplifiers
with low-power shutdown mode accept DC-coupled
inputs and drive up to two DC-coupled, 150 back-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 1A, making the MAX9504A/MAX9504B
ideal for low-voltage, battery-powered video applications.
Output Current Capability
As shown in the Typical Application Circuit, the
MAX9504A/MAX9504B can drive up to two 150 loads
to ground at the same time because the outputs can
source guaranteed 45mA (min) current. Two 150 loads
to ground is the same as a single 75 load to ground.
Since the MAX9504A/MAX9504B can also sink guaran-
teed 40mA (min) current, they can also drive two, AC-cou-
pled 150 loads. 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 Mode
The MAX9504A/MAX9504B feature a low-power shut-
down mode (ISHDN < 1A) for battery-powered/
portable applications. Driving SHDN high enables the
output. Driving SHDN low disables the output and
places the MAX9504A/MAX9504B into a low-power
shutdown mode. In shutdown, the output resistance is
4k (typ) due to the combination of feedback resistors
from OUT to ground with FB connected to OUT.
